The Gospel Chimes were Jessy Dixon's group Roburt. I've listened to their Hob albums this morning and there seems to be quite a few lead singers on those recordings (including James Cleveland, Dixon, Claude Timons and now Lee Charles!) and it would take a while to work out who was who and where Lee was, but interesting that he sang with them and is on their recordings. There is no mention of him on the albums since the Chimes were recording all of Jessy's songs and the liner notes are just a review of the tracks for putative record buyers.
It also opens up the possibility of the Riverside LP of Lee Charles singing spirituals also being our man as well.....
Good addition to the Lee Charles story!
PS: Dave, the Barry White Lee Charles is a UK guy isn't he?
