Hi Don,
I also have the show (but just a 3CD copy and no sleeve...), and I agree with you that Peter's playing is very tasteful!!
I'm sorry but I have no information about a possible release..
Peter also played with The British Blues Masters at Notodden Blues Festival in Norway, after the Royal Albert Hall show. Also there the reviews were not very kind. The show was supposed to be aired on Norwegian radio, but I've checked ever since, and nothing has ever come. And I haven't heard of bootlegs of that show. Anybody??
Daniel
