Not certain but there it is something similar in the voices, great artist, jimmy bailey as evidenced on this lovely ballad, it's the closest I can currently find to connect the voice. Jimmy seems to have been struggling commercially around '68 when funny girl was recorded? I'm assuming it would have been hot on the heels of the movie to cash in, possibly early 69. He had just one release on calla and one on Mala in '68 so perhaps he was sessioning, I can imagine with he would have been in demand with his range and versatility.
