Are you noticing a bunch of great bands have literally fallen apart in the past month or so? I hope you got to see 'em before the "you know what" hit the fan.
AC/DC (caveat: things could still change)
CSN & Y (cos let's face it, Nash and Crosby were the only two you could ever really count on to wrangle the other two back into the fold)
The EAGLES (no Glen Frey = no Eagles)
