In October, Harry Shearer sued Vivendi, the company that owns the rights to the film This is Spinal Tap. "In the lawsuit," notes Rolling Stone, "Shearer claimed that, over a 22-year period, he only received $98 for his contributions to the soundtrack and $81 from merchandising income. The income he generated from his share was 'about enough to buy one miniature Stonehenge,' he joked."

Now, costars Christopher Guest and Michael McKean have joined the suit, along with the film's director Rob Reiner. The four are now collectively seeking $400 million in damages.

Among the artists on deck as curators are Elton John, George Clinton, Quincy Jones, Talib Kweli, and Sean Lennon. A portion of revenues will go to charities designated by the artists. (Billboard)
