Have just done exactly that, but if anyone else wants to answer the question please feel free.
I've no idea, but why not mail Keith and ask (email address should work a@b.com)?
I hassled uncle to send me the whole set a while ago, it could pop up as a torrent I guess?
I'm nailing these today!http://hypem.com/#/track/685770/Petra+Haden+-+Don+t+Stop+Believin+
I'd quite appreciate the whole set as a torrent?
