In my youth I remember being seriously pissed off if I went to see a band and it was missing some members. Once, for instance, I went to see the Walker Brothers (OK, you need to be old to remember them) and it was just the cheeky younger brother and some pals -- he wasn't even in the original line up!

These days, however, I couldn't give a rat's arse who's in the band if they're good musicians and they play good stuff.
