I was a member of a band for the past six years. The band is a sole proprietorship and I was paid as contract labor(I file a 1099 with my taxes). The band has never had any kind of formal written agreements of any kind. While we were together we recorded 2 CDs. - all the music that was recorded is in the public domain. We had no recording contract for the CDs. We just did them on our own. I recently left the band to join another band. Am I due any money from my old band for my performance on the CDs, that they will continue to sell? If yes,what percentage?
