During my last few long runs I have been listening to two John Martyn albums on shuffle.
Grace & Danger contains the original version of 'Sweet Little Mystery', which was made famous by Wet Wet Wet. In my opinion the original version is in a completely different league to the cover.
I only discovered his music while I was watching a documentary about him a few months after he died. I've been slowly acquiring his albums since then. I have a few more than I have listed above but I haven't transferred the files to my phone for listen on-the-go (I'm going to do that now).
