Julie Driscoll/Brian Auger 15 minute live audio bootleg 1968

Hi there,

Don't suppose there are any fans of Julie Driscoll and Brian Auger that know anything about a live audio tape of a 1968 show that apparently surfaced in 2007? Long gone SHTV member peelmeanemma mentions it in this post from a decade ago: Colour Me Pop UK TV

I'm looking to track it down as as peelmeanemma speculates, it may have been the soundtrack to Driscoll and Auger's all live (filmed at Fairfield Hall in Croydon) appearance on my most wanted mostly missing TV show, Colour Me Pop. Any help identifying where (if anywhere) this tape can be found and it's contents appreciated!
