Wish he'd just abandon the idea of doing the high notes and just fully commit to singing in a lower register where he still has power. Build the setlist out of songs that are in that range – It's So Easy, Bad Obsession, Mr Brownstone etc – and rework the others to sit in that range like he did with Nightrain and Estranged at that one London gig where he was ill. Obviously you'd have to keep SCOM and probably Paradise City in the line-up, but two songs isn't going to be too taxing.

Idly wondering – apropos of nothing – what a setlist tailored to Axl's lower register would look like. Obviously you could transpose some of the songs as he did at that London show where he was ill, but is it possible to actually put together a decent setlist that wouldn't murder his vocal cords?

Be fair, some of the stuff on Duff's solo albums is great. Tenderness, Chip Away and Don't Look Behind You could all have gone on a GN'R album if they'd simply had Axl singing the same lyrics and whacked a Slash solo on them. (I loved the Walking Papers albums, they may be the best stuff Duff has ever done, but I get the feeling that's very much a Jeff Angell project with Duff laying down some bass tracks).

Slash's solo albums have some good riffs on them, but Myles' lyrics and delivery set my teeth on edge, mostly. I quite liked Wicked Stone. Anastasia's very good musically, but – crucially – doesn't feel like it'd sit comfortably on a GN'R album, with its Bach-esque scales.

Axl does sometimes go overboard a bit on the production side of things, but it does make the modern GN'R stuff musically interesting, as with Monsters, The General, and the intro from CoTR. Left to his own devices Slash seems perfectly happy just belting out rock riffs and letting the singer do whatever over them; Axl's the one adding the woo-woo fairy dust of movie dialogue samples and mad industrial synths that elevate the tracks.

Well, he's played in Duff's band so you'd hope the chemistry is there – and the interplay between the bass and drums is the most important factor. It'll be interesting to see how it plays out!

Cue everyone frantically looking up clips of Loaded playing GN'R songs...

I remain genuinely baffled that Grohl's infidelity is an issue. He's a rock star, for crying out loud, it's practically in the job description.
