Expertise:  I can answer questions on *most* of Frank`s recorded output and live performances including information on band members also. I cannot answer questions on the technicality of Frank`s music or playing as I am not a musician.

Experience in the area
I have been a fan of Frank's music since the mid 70s and own most of his recordings either on vinyl or cd.
I have seen him live 4 times and have numerous live recordings in my collection.
If I don't know the answer to a question immediately I know of a number of internet sources and trading friends where I am confident I can find the relevant information.
