Whilst I love Martin's work for it's own sake, Micca's message pretty much says it all:
Having spent ages trying to find some hugely obsure recordings of 'Walter Pardon' (A Norfolk Folk Singer), I approached Martin at a gig, and explained the situation. He advised me as to the best place to locate them, but if I couldn't, to get back to him.
I couldn't find them, and within a week got a copy of the album, free of charge.
The loveliest thing is that, as Micca mentioned, he'd be hugely embarrased to read this.
