Once Too Often or Slaughter on Tenth Avenue
This movie is not that popular but I think some of the dance numbers were very good. I especially liked Once Too Often. It was sung by Betty Grable and danced by Betty Grable and Hermes Pan.
Who is Hermes Pan. Just, imo, the best choreographer in Hollywood history. He was the choreographer in Kiss Me Kate, Silk Stockings, Flower Drum Song, and many, many others. I think it's very rare to see him also dancing.
The movie Words and Music featured Slaughter on Tenth Avenue danced by Gene Kelly and Vera Ellen. I think that Kelly was the choreographer.
Here's a vote for "Once Too Often." I thought that Grable and Pan together were marvelous.
