Camryn Newton-Smith is us.

Like we'd do towards the end of a night out, the Australian heptathlete sings along to 'Mr Brightside'.

Difference is she's preparing to run at the high jump bar in the Olympics.

She comes out of her cage and she's doing just fine - clearing 1.80m.

He went out in the semis of the men's 100m but Louie Hinchliffe is back in the 4x100m relay squad.

Richard Kilty is also part of the team, and they both spoke to BBC local radio before heading to Paris.

Great Britain's men's 4x100m relay team spoke to BBC Sport after they qualified for the final.

Jeremiah Azu: "I got another chance to come out here with the guys, it is a shame what happened [in my individual 100m being disqualified], but it is track and field so we learn and move on.

"I have got a long career ahead of me, so I will use that pain to fuel me. I set up the guys nicely and we are into the final."

Louie Hinchliffe: "We are into the final which is the main thing. Survive and move on."

Richard Kilty: "It was amazing to get out here with these young flying-machines. Fastest time of the year and we will definitely move it on for the final. Much more to come."

Nethaneel Mitchell-Blake: "It was tighter than I would have wanted it to be, but the main thing is we are into the final. The commandry is great with each other, now its an opportunity to try and do something special."

Katarina Johnson-Thompson looked fantastic. Her runway looked smooth, light and bouncy - that real flow in her running. She attacks the bar and gets such great height. She cleared that with absolute ease.

• Jade Jones is about to begin her taekwondo campaign for Great Britain, after team mate Bradly Sinden safely came through his round of 16 bout.

• GB's Grace Reid and Yasmin Harper progress to 3m springboard final.

Easy as you like for Katarina Johnson-Thompson.

Second jump, at 1.80m this time, and a second comfortable clearance.

USA's Anna Hall fails to clear 1.80m at the first time of asking but defending champion Nafi Thiam joins at that height and makes no mistake.

Up next for GB in the taekwondo is Jade Jones against Macedonia's Miljana Reljikj.

Jones is bidding to become the first three-time Olympic champion in the sport's history, having suffered a heartbreaking early defeat in Tokyo three years ago.

She has said that she didn't know how to deal with the expectations on her in Tokyo, and she ultimately took a break from the sport, before moving to Croatia to train under a new coach.

It's borne instant rewards - she won her first Grand Prix event in five years last year, as well as European gold.

Jones was cleared to compete in Paris after it was decided she would not face any sanctions over a doping violation.

She was provisionally suspended after failing to provide a urine sample, but UK Anti-Doping said it had been presented with confidential medical records that showed Jones bore "no fault or negligence for her refusal or failure to submit to her sample collection".

Yasmin Harper's final dive is her worst so far but she has done enough.

Now can Grace Reid join her in the final?

You bet she can!

Whereas Yasmin Harper struggled on her final dive and crossed the metaphorical qualification line with a splash, Reid soars through.

It means will be two British women in Friday's 3m springboard final.

Reid progresses as the seventh-best qualifier. Harper's error on the final dive means she scrapes through in 12th.

Once again, China top the standings. Chen Yiwen, the gold medallist from the synchro, qualifies with the best score.

KJT means business.

The Olympic record holder comes into the high jump competition at 1.77m and casually clears the height at the first attempt.

Barely took a breath!

Little reaction from the Brit, who looks focused and firing as she moves into the lead.

A reminder that her Olympic best jump is 1.98m.

Great Britain's double Olympic champion Jade Jones will begin her pursuit of a third crown in the taekwondo women's -57kg event at 11:00 BST.

The Welshwoman will be in round of 16 action against North Macedonia's Miljana Reljikj.

Wow.

Big shock as Jamaica fail to make it through to the final.

China win heat two in a season's best time with Canada and France also through to the final.

It was a much slower heat so fourth-place is not enough for Jamaica to even snatch one of the fastest loser spots.

No problems for Katarina Johnson-Thompson are she easily clears 1.77m with her first jump.

The British world champion did bid her time before entering and will hope to keep going for a good while yet.

USA's Anna Hall also cleared 1.77m but her team-mate Chari Hawkins takes no points from the high jump after three failures at her first attempted height of 1.71m.

Ouch! That was tight in the men's 4x100m relay.

Not for the United States but everyone behind them.

British anchor Nethaneel Mitchell-Blake anxiously looks up at the screen as we wait for the decision of the photo finish...

His smile, the roar of many in the crowd and Union Jacks being waved greets the news.

The instructions from the US coaches would have been 'get us into the final, nothing risky' their team when they bring in their big guns could be very close to that Jamaican world record.

Just!

Team GB squeak through in third as Nethaneel Mitchell-Blake just about manages to hold the chasing pack on the final leg.

The USA, unsurprisingly, win it comfortably but a messy second changeover meant GB briefly led when Louie Hinchliffe handed over to Richard Kilty.

A solid first leg from Jeremiah Azu as well as his false start nightmare in the individual event.

Season's best 38.04 for the British quartet, South Africa were second in 37.94.

Japan - just 0.02 behind GB - and Italy must wait to see if they went quickly enough to make the final...

We all know the rules - false start and you’re out.

But it was so hard not to feel sorry for Jeremiah Azu at the weekend. A cruel way for your first Olympic race to end.

Thankfully, he has another chance. He’s part of the GB men’s 4x100m relay team going in the heats this morning. You know he’ll be desperate to show what he can do this time.

A painful image for British athletics fans because, of course, the men's 4x100m relay team of CJ Ujah, Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake were stripped of their silver medals three years aog.

That was because a doping violation against Ujah. He was banned for 22 months after testing positive for two prohibited substances at the Tokyo Olympics - but he was cleared of intentionally doping.

Ujah is not in the squad for Paris but Hughes, Kilty and Mitchell-Blake are all back, hoping to avenge the events of the past three years.

With Louie Hinchliffe and Jeremiah Azu also part of the relay team, Hughes - who withdrew from the 200m with a hamstring complaint - is the one to miss out for the heat at least.

Whoever makes up the British quartet, they will go in heat one at 10:35 BST - any moment now, basically...

The USA and South Africa are also in heat one. Top three qualify automatically.
