The DU Lounge

...he got into it with Robin, and to a lesser extent Rick.
Rumor was that Robin did a "him or me" to Rick & management.
Figuring it was easier to find a good drummer than a new "voice of Cheap Trick", Bun E was unceremoniously dumped.
A few years later he sued under the claim that the original agreement was that the band's company owned the songs, so as 35% owner he was entitled to royalties.
The out of court agreement was he would keep his 25% ownership, but would not return to the band ever & could not use references to Cheap Trick for his own projects.
So, there is really no chance of a reunion. Too much bad blood.
And, from what I was told, Bun E doesn't play that well anymore because of a bad hip & arthritis.
