In reply to Neil Orman's post on Wed 16 Feb 2011 :
If it is just that one clip, you can send it to me and I'll send it back. I probably can completely get rid of it in Pro Tools, depending on what it is.
If you have Final Cut Studio, Soundtrack Pro Audio Restoration can lessen or remove it.
Music – You would need permission to use the recording, unless you record/perform the music yourself. Someone on here knows more than I do about the legalities.
Can't answer the Vimeo part...
