I agree with Sadie4, I felt inclined to say What goes on, but I'm pretty sure the reason I like it is because of the amazing harmonies done by the others! That wouldn't be fair, would it.
I really like If you've got trouble as well - but that again is because I like the riff... Hoh, this isn't easy
Best solo song would have to be Instant amnesia, quite definately.
You can have my love, you can have my smiles. Forget the bad parts, you don't need them. Just take the music, the goodness, because it's the very best, and it's the part I give most willingly.
