Amazing that as soon as I heard it, I thought it was Gladys. It sounds like the Gladys heard on the unreleased "Learning To Forget You" and a bit like "I Need Someone". The song is cut in a higher key than I'm used to hearing Gladys sing and maybe that is why she sounds so un-Gladys like to some ears. (and wouldn't it be typical of my life if someone came out right now with proof this ISN'T Gladys!!!)
