If I was a betting man, Id say that version of Better was recorded between 2001-02.
Originally I thought Catcher could have had Fortus on it, because that thundering rythym guitar riff right before the Na Na Na's, which seemed far more like his style than Paul Tobias, however Axl's vocals sound certainly dated.
TWAT is the hardest to tell if you ask me....
It could be Tobias or Fortus...to hard to distinguish on this one.
Id say it's older than Better, but I wouldnt put my money where my mouth is
One thing to remember: ?tracks do not, necessarily, need to be recorded all at the same time.
Which means Axl's vocals could be circa 2000, while the rhythm guitar track could be circa 2003, and the lead guitar track could be circa 1999 (all just examples, not guesses of actual recording times). ?
Then someone (I'd guess Axl) takes all the tracks and puts them together.
