Pogue, Kelly is out on CD on the Original Cast label (the
other Bruce's label

). The liner notes are fascinating. Charlap insists it was a hit, it just didn't run, LOL. And there are some bonus cuts, including Mrs. Charlap, Sandy Stewart, singing the big ballad, which, again, he claims was a top 40 hit, but I have never been able to find in Whitburn, LOL
Perhaps you know this already, but Charlap and Stewart's son is a jazz pianist of the first order. He is known to do songs from Kelly occasionally in his sets.
