Maybe the "reason" they split up was the old, classic & for the most part oft used reason/excuse/explanation of "artistic differences" which tends to get used with most bands/members when they need a break from each other (like a vacation wouldn't do the trick? , hell, some bands take years off/away from each other and/or in between recording sessions, tours or P.R. stuff), but it may have been the boozin', the broa...(no offense to the any/all ladies ) er, ladies & then you have the record exec's wanting/waiting for the next "hit" single or record, lol, cd, well, whatever. Oh, & then there's that little thing named druuuuuggs' involvement for all the ingredients of a split up, not to mention probably lack of ideas for new material, in some cases. Thas IMO, of course I could be wrong!
