Michael Anthony, bass player and founding member of the band Van Halen, was pretty much screwed by his bandmates early on in his career. There's much confusion surrounding the story, but halfway through the 1984 tour, Anthony was forced to give up future royalties and credits for any new Van Halen material, as well as retroactively release any claims to Van Halen's music. Then in 2004, for a Van Halen reunion with Sammy Hagar, in order to be included, Anthony signed a contract that treated him as little more than an employee. When he was finally fired from the band, he found out by seeing it posted on the internet. Michael Anthony didn't seem to suffer too badly from the poor deal, his net worth is around $50 million and has been involved in projects like Chicken Foot with Sammy Hagar.
