Teddy & The Counts
This obscure New York group only ever had just this one 45 released – and it is now a very pricey item. Theodore “Teddy” Wilson had a super gritty voice well suited to this deep ballad and the Counts harmonize well behind him. I guess the session didn’t run to a horn section as The Heart Is But So Strong has only a small rhythm section on it, but the vocal packs enough of a punch that this doesn’t matter much. Flip is a version of the old Soul Survivors classic “Expressway To Your Heart”. It was produced by veteran Al Browne for his own gallant little RAB concern.
UPDATE ~ Mike Cassidy has found this Wiki entry for Theodore "Teddy" Wilson here. If this is the same guy - and it surely must be - then he had a much fuller and more successful time as an actor than he ever did as a singer. I'm grateful to Mike for his sharp eyes.
