A separate comment, not related to the quality of the performance: I found it amusing watching the lead singer keep his head and mouth perfectly positioned for the mic even while moving the rest of his body around, something only a seasoned studio singer would do properly. His facial hair created an impression of the head appearing large for the person's body, and in combination with his checkerboard shirt, and the head remaining mostly still while the body moved, it created a weird effect as if someone has substituted someone else's head over the person's body in the video.
Buddy Greco's verson of Rodger's & Hart's "The Lady Is A Tramp" originally recorded by Tommy Dorsey and His Orchestra (featuring Edythe Wright on vocals). Buddy sings and plays the piano on this one, and IMO not only sings it wonderfully, also accompanies himself grandly.
The first time I came to Las Vegas, probably early Nineties, I saw Buddy Greco. He was playing one of the bar lounges at, I think, the Flamingo. Just a 3 piece. Pretty cool. It was after we saw Wayne Newton at the Hilton theater.
