Band breakups are as much rock and roll tradition as drugs and trashing hotels. Some groups go on hiatus only to get back together within months while others make the permanent split. Forever is a long time and the lure of money and one last shot of fame often reunites bands more often than not.
Why do bands break up? Sometimes it’s jealousy (one member stealing the spotlight), straight up fighting or money distribution. For a band to never get back together it has to be bad, so bad that even money can’t make it happen. Some bands have successfully split and made up to finish out their legacy (and get paid), others have made attempts only to falter, realizing why they split in the first place. The success stories include the Eagles, Black Sabbath and Motley Crue.
