Overheard in the members' area: "Jeez, you're a bad bloke, the poor guy asked for a water and you've got him a beer." 'Bad' substituted in for something unprintable.

Pat Cummins has gone past his highest Test score, which was the 42 he made last week in Brisbane.

Steve Allen: Someone tweeted to you who else is dragging their duvet on to the sofa. I’ll be dragging mine over my head when England bat

Stuart: Poor from England. Same story as the 1st test. Missed opportunities. This has the feel of 5 zip all over again

Marsh has been the rock in the middle order for Australia. He has steadied the ship again.

Gary Douch‏: We need to bat for two days, score quickly and bowl the Aussies out cheaply, otherwise the Ashes are gone.

It's early days, but we've been here enough to get a feel and sense of a tour. The first innings will be key. If England can get somewhere close to Australia, the third innings will be tricky for Australia.

Reasons why the Adelaide Oval is one of the best grounds in the world, number 63: You can do a whole lap of the ground - at the back of the bottom tier of seats on the concourse - and have sight of the cricket all the way around.

If you're just tuning in, then, er, I'd go back to bed. Here's how the first two sessions have gone down.

• England took a wicket with the third ball of the day, Stuart Broad trapping Peter Handscomb lbw for 36, before Shaun Marsh and Tim Paine rebuilt.
• Paine overcame several blows to the hand but holed out on the stroke of tea for 57.
• Mitch Starc came and went but Pat Cummins has provided fantastic support to Shaun Marsh, who brought up a classy century just before dinner.
• Alastair Cook just looked like he had taken a catch at slip to remove Marsh, but had it knocked out of his hands by James Vince, who dived into him. There's a sentence that sums up a day.

And that calamitous moment comes on the penultimate ball before the dinner interval. Another excellent session for Australia. They've added 103 runs and lost just the one wicket.

Was that the session we'll look back on as the point England lost the Ashes?

It feels like that will be the image of the Ashes. It will be replayed over and over.

That could have been nasty. The way they collided - we've seen incidents where that could have been really messy. That sums England's day up.

Deary, deary me. A bouncer from Chris Woakes to Shaun Marsh. It's good, right at the throat and Marsh fends it up in the air. You feel the ball has to drop to hand but it drops right between Alastair Cook running round from slip and James Vince at gully.

Cook gets his hands to the ball and it's almost in his grasp but Vince has eyes for the ball and collides into him. It's hard to say whether Cook had the ball under control but that just sums the whole thing up. The ball hits the turf and the crowd laugh.

England are going to bowl some short stuff from round the wicket to Pat Cummins in what is likely to be the final over before the dinner break.

Craig Overton is back once again to give a spell another go. It's a decent over. Twice he finds the inside edge of Shaun Marsh's bat but the ball skews past the stumps to fine leg. Overton is frustrated and waves his arms around halfway down the pitch.

Australia are 12 runs away from the highest first-innings total in day-night Tests in Australia.

Balance on the front foot, got the gift to play on the off and on side - Shaun Marsh is probably a player who, over the years, has been very frustrating. He's never really kicked on and had that dominance. Maybe that time is now.
