Liza Minnelli - For Me And My Gal = Gene Kelly An American In Pasadena 1978 (78010)

This is a short memory lane clip.
 
Liza Minnelli is the daughter of Judy Garland. This alone is remarkable, but originally Judy Garland and Gene Kelly played Vaudeville performers in the 1942 Musical Film For Me And My Gal. That makes this performance special.
 
"Why didn't you tell me I was in love with you?"
 
Tony, Emmy and Oscar would lose their minds. Who did Liza Minnelli work with in the late eighties?
