Have been offered some unpaid work to film a tribute concert / comp for MJ - 'Nav' a impersonator of MJ who performed at his birthday will be performing. The woman has said i can produce a dvd and then i get a % per sale of the dvd. Ideally id want to sell myself, sell the license to other retailers - what issues must i address ? Using MJs image? Using MJs music (recorded at the venue through the camera VS using original track dubbed over - any dif?) Using Nav - lead artiste (would need him to sign something?) its this sunday so not much time, thinking i film it and sort out other stuff after?
