Legal question on usage of my studio work by a former band
So I recently got let go from a band I was working in for about 2 years. The band leader is on a small independent label which distributes his recordings. I know it's hearsay, but I started this recent band with him and came up with the name. He writes the songs, all other musicians write their individual parts. I've done everything from promoting, booking, making posters, photography, facebook support, etc., so I was not just another hired gun. I laid down tracks for 13 songs, one of which was released as a 45 on the label and I was given credit as the bass player. I never signed a thing or received a dime for those record sales. Now he's got 12 other songs he's going to release as a CD. I asked him not to use my tracks after he let me go, he agreed (we'll see if he honors that request).
Basically, the question is: do I have rights to anything he releases with my tracks on it? Did I give up my rights by not signing anything? I've known him for almost 20 years and didn't feel he'd screw me over, but it happened. He's getting royalties for the recordings, but no other band member has received a dime from any sales (they are definitely selling). Has anything similar happened to any of you?
