I really didn't mean it! I grew up listening to Soul music and Luther is just an idol of mine god rest him.
I like all them too but Luther's vocals are just sensational. When he released Never Too Much in 1981 I was instantly hooked.
I was a bit young in 81, I heard Cooke's Wonderful world probably when was six/seven and it's still one of if not my favourite songs, and I found Otis after hearing the Blackcrows cover of 'hard to Handle'.
Luther was lead singer of the group Change back in the late 70s before he went solo. There is a fantastic track titled Searching which you may have heard but if not I highly recommend you have a listen.
