Peter Green's royalties

[slipkid]

I've read from those who live in UK that Peter Green's music has turned up on a couple of TV commercials in the past few years. For instance Albatross was used for a grocery store chain, and Man of the World was used for a soda commercial from Ireland. Does Green still control his music, or did he sell the publishing rights years ago? What about Santana's BMW? I'm sure that has provided a steady income over the years. If this has been posted about before, I'm sorry but it was a question that crossed my mind.
