I couldn't agree more, and he is just so much fun - along with Fred Astaire and Eleanor Powell - in "Broadway Melody of 1940".
Surprisingly my favorite Duo tap dance in Broadway Melody of 40 is Don't Monkey with Old Broadway - - Danced by Fred Astaire and George Murphy.
Murphy holds his own with Astaire and doesn't seem intimidated or out-danced in the least.
They look like two hoofers having a good time doing a number that was just written for them by Cole Porter.
By contrast - - Fred Astaire's dancing with Eleanor Powell looks disjointed. In this one particular case, he allowed the lady to emphasize her style of tap dancing and not his. Probably because he never had worked with a female tap dancer who danced as well, if not better than he did. ( Although Rita Hayworth was very good.)
The other instance I'm thinking of is in The Bandwagon--when Fred does a duo soft shoe number with the famous English song and dance man Jack Buchanan-- I guess I'll have to change my plan. Reportedly Buchanan was scared to death to dance with Astaire and you can see like he really was sweating buckets during the number. Although it came off alright, he didn't look like he enjoyed it very much.
I grew up watching George Murphy dancing with Shirley Temple in Little Miss Broadway and he always impressed me as an elegant and accomplished dancer.
Reportedly he gave up dancing in the movies after losing so many in roles to Gene Kelly and seeing that he had no future in it.
So he decided to go into politics-- apparently convincing two of his old movie-star friends, whose careers also had hit a dead end, to go with him--Ronald Reagan and Shirley Temple.
