Back when I put my Haywood compilation together, this disc did not exist. It claims to be complete and does indeed have the one track that I knew that I was missing, but it omits the 2 unissued tracks that Kent unearthed so I have included those to make it complete.
"Joe Haywood was a Bad-Ass! In several different compilations and a few 45's, I had become limitedly aware of the singer Joe Haywood, but only recently did I focus on building something in the way of a compilation. Without the fine work of Red Kelly's soul detectives, this idea would have likely been a still birth. Between Red, Larry Grogan and Sir Shambling, I picked up the information necessary to start digging for as many of the tracks as I could find (1 more 45 is in transit that will supply a missing track and get us to 21 but I couldn't wait any longer). It is possible that there are multiple versions of a few tracks, but so far they have all been licensed re-issues of the same recording." earlier write up
By far the best biographical info is here:
