Does anyone happen to know who I should be trying to track down in order to secure licensing for recording a cover of "The Pussy Cat Song?" See, the version he plays includes a few extra verses that are locally oriented, and if I understand the rules correctly, we actually need more than just cover rights, we need the rights to create a derivative work. Who on earth do we contact? If it's true (as mentioned above) that this was recorded in the 1920s, then we're in the clear - but I don't know this for a fact. We're trying very hard to keep everything above board, but folk music is tough to track down sometimes!
