Looks like you're sorted with this one Tone.
I was going to say you're welcome to "borrow" my copy so to speak, if need be, especially if you need it for research.
Definitely a blue eyed artist of course, but it's a very creditable up-town early 6T's New York sounding disc, and he obviously was inspired by Ben E King's sound.
Deep In the Heart of Harlem ? Sounds like an interesting project. Are you able to elaborate ? Hope Clyde McPhatter's absolutely epic LP "Songs of the Big City" on Mercury features prominently, one of the great soul / R n B LP's ever.
