a band of three members composed five song.the basic composition which includes the lyrics the way of singing and the chord structure was of the vocalist. now the vocalist left the band. and asking for the credits and rights. songs are not yet released. I produced the songs. how should be the rights should be distributed among us ?
It's very simple, as per your 3 members agreement whatever the returns you get must be shared accordingly. There will be a Royalty, any live concert conducted must pay.
It's all depends upon you 3 as agreed. The person who left can relinquish the rights / royalties at his free will but, his / her name must be acknowledged and published.
Frankly speaking, I don't like the current state of copyright laws. There are so many questionable aspects. I even heard that in some cases when you turn off a radio or play a tape you can violate the law. I'm reading here about the best stereo receiver and I'm not sure that I will use it without any troubles.
