A GAP OF TWO YEARS ISN'T A 'SPLIT'; SOME BANDS SPEND LONGER THAN THAT WAITING FOR THEIR MAN: They only broke up in 2002, but it seems that the Black Crowes are on the point of reforming. Is it just us, or is the concept of "breaking up" being a little tarnished these days? "Oh, we're breaking up" announce bands, even while they're booking tours in for the following Fall. Shouldn't there be some sort of rule made that if you split, you stay split. For at least, I don't know, five years?
