The Lost Portfolios!- JOHN LENNON "Not A Martyr"

Coming up to the end of the "lost portfolios" project, this is the 2nd to last bootleg I found and a strange one at that. As you can see above it says King Bisquit Not A Martyr on it. I have no idea what this is from besides the fact that it's obviously some kind of radio broadcast and it has a combination of live music and interview with John. Might be from MSG NY 1972 but I have no other info, I checked out a little bit of it though and it definitely sounds like a cool show and interview. Link. Note this is not an official release and is suitable for trading.
