Agreed about Desert Island Discs being iconic. I went through a phase of listening to some early episodes and I am surprised MK has never been featured until now.
However, I fear this interview may just be a compilation of all the little anecdotes we all know already....."1st guitar was a weeks salary", "didn't want to mention an amp", "blew up the family radio" "Uncle Kingsley....Boogie Woogie"...."you've got to really want it".....
We do need a few new stories and an interview in this setting may just unlock the MK archives....
