The band Beatallia met a similar fate
That is to say, they're still alive and rocking.
Beatallica brilliantly fuses The Beatles and Metallica into such easy-listening ditties as "Blackened the U.S.S.R.," "Leper Messiah," and the timeless classic "Hey Dude."
A few years ago a lawyer from Metallica's record label — surprisingly, perhaps, not The Beatles' — sent them a cease and desist letter along with threat of a multi-bazillion dollar lawsuit. In the end, Lars Himself intervened, and saved Beatallica from an ungodly end.
Beatallica is going to play at Club Garibaldi in Milwaukee on 25 Feb '16, so if you're in the neighborhood, swing by and rock out. They're online at http://www.beatallica.org/.
