Hi. I'm a newbie video editor and am editing a couple's holiday film. They went to Africa and while they were there saw various live bands at events they attended. One band was playing a promotional show in a record shop. The music is great and really adds to the film but I'm concerned about the copyright issues. Is it OK for me to use this music and if not - how do I go about resolving the copyright problem? I don't know the names of the bands..... Any advice much appreciated!
