The semis are sorted, the goal of the competition might be sorted too, and we're all away to our bed.

Graham Carey, thank you for brightening up a dull second-half. That goal was worth the wait.

Until next time, folks.

Livingston manager David Martindale tells BBC Scotland: "You've got to give Graham Carey a but of credit, it's a wonderstrike.

"Spoke about him during the week to be fair and was delighted he wasn't starting, I think he's a big player for them and he always creates something.

"There's not many players in Scotland you'd probably allow to shoot from there, he's one you don't. We couldn't get any pressure on it because we've cleares the ball from out box so you;ve got to give Graham huge credit.

"I think the difference in the game tonight is probably the top end of the park, talking about the top end of the park, he's nearly scored it from the middle third.

"Andy Fisher kept them in it I thought he had two great saves, and then I think we've got to do a bit better ourselves, Robbie Muirhead had a great chance, I think he's got to hit the target as does Andrew Shinnie.

"What I will say is it's a stonewall penalty in the first half that we never got because that's really, really disappointing because I think it was an easy decision. We could see it form the bench in realtime so I think the linesman's got to see it, we bit more difficult from the referee.

"And then if it's a stonewall penalty there wasn't a genuine attempt to win the ball so potentially that could lead to a red card. Som felling a bit sorry for ourselves in that respect."

St Johnstone goalscorer Graham Carey tells BBC Scotland: "It was a good strike, to be fair I've been long overdue a goal like that.

"Throughout me career I've scored a few like that and haven't really lately, so it was a great touch from [Jaosn] Holt and when it sits up like that you just have to hit it.

"Second-half performance was better than the first half, we started passing it and creating problems [for Livingston].

"If it wasn't for Andy [Fisher] we'd probably be out of the tie, so thankfully he kept us in it."

St Johnstone manager Simo Valakari tells BBC Scotland: "First of all, we should talk about Andy Fisher's saves in the first half - he kept us in the game. There was some great defending first half as well.

"I see it [Carey scoring] every day in training. What a player. He's got an extra special left foot. Beautiful, and we needed some magic tonight.

"Big credit to Livingston, they put us under pressure.

"It was that we are still strongly in this tie. We knew we needed to do things much better. We didn't have the quality to play under their pressure. We knew they'd press, we could not find second balls, could not find flow or rhythm of our game.

"Second half, everything changed. It was much easier for us. We were not right tactically first half. It looked like we didn't have energy.

"We changed our defensive shape and our players looked much more aggressive, we started winning balls.

"There is no weight on our shoulders in the Cup. In the Premiership, we fight for our survival.

"Barry Douglas said in the dressing room, you think as a young player you'll get many opportunities, but your career goes fast. You might never get the chance again. Now we can enjoy it."

Anything can happen, they'll [St Johnstone] go there with plenty of confidence. They're not going to change their gameplan.

If Graham Carey plays and he sticks one in the top bin you never know.

They'll just be delighted to get back to Hampden.

That Hearts v Aberdeen game could be a cracker. It's two teams who have had really good period and moments throughout the season.

They'll be happy they've avoided Celtic.

But listen, if you're going to win the Scottish Cup, you're probably going to have beat Celtic.

Here's a little stat I was furnished with earlier, regarding Hearts and Aberdeen.

It's just the third ever Hampden meeting between the two. The previous two being the 1986 final and the 1996 semi, both in the Scottish Cup.

They met in a League Cup semi decades ago, but it was at Easter Road.

That leaves us with...

St Johnstone to play Celtic.

Right, here's the draw.

Hearts will play... Aberdeen.

I felt there was a bit of mentality change from St Johnstone [in the second half].

They got in Livingston's face as much as possible and the back three were excellent, they stopped that threat Tete Yengi was carrying in the first half.

Most certainly a goal of the season contender.

You knew as soon as he struck it, he knew it had a chance. Wow, what a goal.

So there we have it, our four semi-finalists - Hearts, Aberdeen, Celtic and St Johnstone.

The draw will get under way shortly, but we'll get some reaction first.

Graham Carey puts the magic into the phrase 'the magic of the Cup'.

A better strike you will not see, as he lasered the ball into the top corner from 30 yards out. A goal worthy of winning any game, and a goal worthy of sending your team to the national stadium.

Big shout for handball as Ryan McGowan's header is blocked. Not given by referee Don Robertson.

The resulting corner is well cleared. Livingston pressing, at least.

A triple change now for Livingston, with Reece McAlear, Meshack Ubochioma, and Matthew Clarke all coming on.

Cristian Montano, Andrew Shinnie and captain Jamie Brandon are replaced.

Time running out.

That should be 2-0 and game done for St Johnstone!

They attack down the right through Jason Holt and Makenzie Kirk, with the former cutting the ball back to Drey Wright six yards out, but he leans back and skies it.

St Johnstone boss Simo Valakari was decidedly stunned by Graham Carey's peach of a strike.

Now Scott Pittman is off, with Robbie Fraser on, and Cristian Montano is punted up the pitch.

It's Plan B time for Livingston.
