He wrote and produced "Nine Times" Pete, among many other of the Moments greatest, er, moments.
Don't think he was ever actually in any incarnation of the group itself, but their history is long and quite tangled. Time has shown that the business practices of Joe and Sylvia Robinson at All Platinum were sometimes quite creative (to say the least), so I wouldn't be surprised if it turns out that he may have actually sung on some of the Moments tracks.
I've never heard any of Tommy Keith's Vibration material, but if it is him on the Wand 45 he had a more than competent voice. I really love "Not Now But Later", the midtempo side on Wand and was gobsmacked when told how rare it actually is.
On a side note I'd be really grateful if someone could post the long-deleted Moments CD-only track "Sleep Won't Come" in refosoul. I'm sure it's just relative unfamiliarity which has held this track back from being a total monster on the allnighter scene. As far as feel-good 70s dancers with instant hooks go it's of the same calibre as classics such as "Nine Times": a magnificent record basically.
