They could easily pad it out with covers, of course. Wichita Lineman, The Seeker, etc. Maybe get Duff to give the band a new solo track, whack a Slash solo on it and call it a GN'R song.

It still annoys me that Duff doesn't sing the backing vocals in the outro the way Izzy recorded them on the original studio version.

One of my favourite things about GN'R is how they vary stresses, emphasis and… syllabic structure? I'm not sure what you'd call it…

The outro to YCBM is a great example; most bands would just sing "You could be mine" over and over, same stresses and emphasis. But GN'R mixes it up; you have Izzy singing "Y'could be mine" while Axl's singing "Youcould be mi-e-ine." And then during the last bit of the song he's basically singing it every possible way you can sing it – singing "mi-e-ine" in an ascending melody, then a lower melody, etc etc. It's one of the things that makes GN'R more sophisticated than other bands, I think.

And he's doing it again with the chorus for Perhaps:
Got a lot more than I bargained for - 9 syllables, emphasis on the "got" and the "lot"

You forgot about the others you were fighting for – 13 syllables, cheeky little run of triplets at the start of the line

Sold out to the ones that you once ignored – 10 syllables, emphasis comes on the second and fifth syllables, "out" and "ones"

You used to be a little crazy, now there's so much more – 14 syllables, with this rapid quickfire run from "you" through to "so" and then a slower triplet.

I'm probably not using the right technical terms there, but what I like is that Axl's playing around with structure.

Oh yeah, I don't deny that he's perfectly capable of laying down studio vocals now, it's just that it's become an article of faith among GN'R fans that he laid down a single vocal take for each song back in 1999 or whatever, and that he never recorded anything else. Which is insane; of course there are multiple vocal takes in the vaults.
