Antoine Dupont is off, with Paul Graou on.

That will only buoy the Glasgow fans. Meanwhile, the Warriors have the throw on the 5m line.

Glasgow are on the rampage! This is one-way traffic.

They break through Stafford McDowall, who pops to George Horne. They're deep in the bowels of Toulouse territory, and they win another penalty.

Hello! Gregor Brown has made a massive difference since coming on.

The guy is an exceptional rugby player - power, skill, footwork, plenty of gas.

He's already brilliant and he's going to be very, very special. Hang your hat on him being a Lion next time around.

We've got a serious game on our hands now.

A few line-breaks as Glasgow start tossing the pill about with gay abandon.

Where was this in the first half?! In fairness, they didn't have the wind in their favour.

Now, they look like a completely different team.

Yes, back to the game, Tom.

Glasgow are going for it now. The home fans thought they'd kicked a 50-22m there, and so did George Horne who is told off by Matthew Carley as the throw is given to Toulouse.

Josh Brennan in the second-row for Toulouse tonight. Was pally with father, Trevor, when Trevor was playing for St Mary's, Leinster and Ireland.

The big man was one tough customer. On a tour of South Africa in 1998 he was getting grief from a local loudmouth and he climbed into the stand to, er, have words with him.

It wasn't the last time he took umbrage at fans. In his last game for Toulouse (where he had great times) he did something similar after an Ulster fan slagged off the quality of pint in Brennan's pub in Toulouse (an excellent spot), Trevor (nicknamed Begbie after the Trainspotting character) wasn't having any of it.

Think he got a five-year ban for that, not that it mattered since he was retiring anyway.

Meanwhile, brilliant team try by Glasgow. Biggest cheer of the night.

Glasgow are down on the 5m line, with a penalty on their side. The whistle blows. George Horne tries the tap-and-go from a metre out, but he's pulled back.

You can't do that, George!

And Emmanuel Meafou immediately gives away a penalty for going off his feet. Not the introduction he would have wanted.

Glasgow kick down to the 5m line. They're knocking on the door!

Toulouse are scrambling.

Indeed, that is Josh McKay's last act. He's replaced by Dan Lancaster, with Ollie Smith already off. A glorious try, but at what cost?

Toulouse change the workers in the engine room, as Emmanuel Meafou and Alexandre Roumat come on for Thibaud Flament and Joshua Brennan.

Quite a surreal atmosphere in Scotstoun at the moment.

There is a full brass band belting out a collection of funky tunes, but rather unusually, they are not doing so during breaks in play but as the game is raging.

I wonder how these toe-tappers are affecting the concentration of the players - perhaps it affected Toulouse there!

Just to bring Glasgow fans back to earth, it was hard to ignore Josh McKay clutching his hamstring as he sprinted over.

That's a concern for the hosts.

Toulouse are pinged for a squint throw, which is met with sarcastic cheers from the Scotstoun crowd.

Meanwhile, Ollie Smith and Max Williamson are replaced. George Horne and Gregor Brown are on, with Jamie Dobie moving to the wing.

That's us under way and Glasgow start the second half well, winning the first turnover and getting the ball in Toulouse's 22m.

But the visitors win the ball back and go from one end to the other, with Blair Kinghorn fielding Romain Ntamack's huge kick.

Glasgow manage to drive it back, but just an example of how dangerous Toulouse can be.

Toulouse have won their last 13 matches in a row during the Champions Cup pool stages (seven at home and six away) by an average score of 44-16.

At this stage, I think the Warriors might just be happy to score 16 points.

The second half is moments away.
