"It's great Usain Bolt has come here. It shows that to him the Commonwealth Games are important and they matter, as we have seen every night here.

"Like David Rudisha as well, it's important to see champions here so people can get out there and race against them."

What time is it? It is Bolt-time....

But before Bolt makes his grand entrance, there's the small matter of heat one to get through. The anchors of Trinidad and Tobago, Canada and the Bahamas streak clear of the rest, but it is the Bahamas who miss out on an automatic spot in the final.

Ten-minute warning. I repeat, here's your 10-minute warning.

That's how long it will be until Usain Bolt strides out on to the Hampden Park track. Wonder what response he will receive from the passionate Scottish crowd after the did-he-say-it didn't-he-say-it saga.

It is confirmed - England are fine. Wales, however, are not. They have been disqualified for a dodgy changeover between Mica Moore and Hannah Thomas. Massive shame for the Welsh because they would have reached the final in a new national record time. Big shame.

"Louise Bloor, as she was coming into Ashleigh Nelson, looked like a long changeover. It was a fantastic first leg by Asha Phillips, they were taking on the Jamaicans. These young ladies from England can really challenge. I think they can get a medal - I think they can even beat the Jamaicans.

"At the Athens Olympics in 2004, we messed up the changeover but the judges were generous and we made it through to the final."

England finish second but there is concern that Ashleigh Nelson didn't grab the baton inside the designated area before hurtling after Shelley-Ann Fraser Pryce. The English quartet nervously stand trackside watching slow-mo replays of the exchange between Nelson and Louise Bloor. Looks fine to me...just.

No surprise as Shelly-Ann Fraser Pryce thunders down the straight to see Jamaica home first. It may not also be a surprise that England are at the centre of a handover controversy...

Next up in heat two are England, Wales and...Jamaica. The Caribbean sprint queens are anchored by reigning World and Olympic 100m champion Shelly-Ann Fraser Pryce.

Nigeria were very sloppy with their changes but if they can bring Blessing Okagbare in..wow!

Time for the event which we all used to love at school sports day - the 4x100m relay. Bahamas win the first heat ahead of Trinidad and Tobago and Nigeria, who were without double 100m and 200m champion Blessing Okagbare. She was having a well-earned rest after her golden exploits over the past couple of days.

Scotland's Lynsey Sharp reveals she was ill overnight before racing to silver in the 800m.

She told BBC One: "This is my everything. The last year has been obstacle after obstacle, even right up to this morning being in hospital in the athletes' village until 5.30. I hadn't slept for 12 hours and was throwing up all night and had a drip in my arm.

"But there was no way after going through everything I have been through I was not going to get a medal today.

"I know how low the low points can be. Yesterday I almost lost it and today I had to come out and get it right. I had 24 hours to get it right and thankfully I did."

Singapore's Gao Ning and Li Hu claim gold in the men's doubles after the top seeds beat India's defending champion Sharath Kamal Achanta and new partner Amalraj Anthony Arputharaj 5-11 11-7 11-9 11-5. It is the only table tennis gold that Singapore had never won in the Commonwealth Games.

Many thought they had seen the last of England's Phillips Idowu when he was one of a number of high-profile GB athletes to lose their lottery funding for 2013-14.

But the eye-catching Londoner is back. After making a low-key return earlier this year, he is back in the big-time in Glasgow. He leads the qualifying stage after a first-round jump of 16.70m.

Tom Daley on BBC Radio 5 live after winning silver in the 10m synchro with James Denny: "It is about what you can do when it counts. Going into the last round, we had to give it our all. We have only done three training sessions together ever and we went in there to have fun. I am happy how we did and to come out with a silver."

On Scotland's Lynsey Sharp winning silver: "Lynsey has had a such a difficult year. She was hospitalised with a wound that didn't heal properly. She isn't always one to tell her own story but it was known in athletics.

"At the start of the season she was struggling to even make the qualifying time but she has raced and raced to get into shape.

"She was in tears after the semi-final because she thought she hadn't run well enough to get into the final. But what a performance tonight."

The countdown to Usain Bolt's first run on the Hampden Park track is well and truly under way. The 4x100m relay first round start at 21:35 BST.

"Get out strong, commit." The four little words scrawled on to Lynsey Sharp's right hand in black marker pen. Not sure she would have had any time mid-race to remind herself of that motto - but she managed to deliver it to the letter.
