What is Joe Strummer playing in live train in vain?

Is it just bad audio? I cant tell what he is adding based on his movements. Its a very simple song, so it seems Mick Jones is playing what you hear.
(Joe Strummer is on left at about :53 if you are unfamiliar with the band)

It looks to me like he’s hammering the shit out of the D-A-A parts of the song, the rhythm part that matches the keyboards.

I’ve moved this from IMHO to Cafe Society.

Yeah. I just dont hear 2 guitars is all.

I think this was a dumb question. I guess it makes more sense to ask what is mick jones playing prior to solo.

He’s way back in the mix, but you can clearly hear him at about 3:14. He’s basically copying the chords of the keyboard part.
