By Judy, is Ms Garland meant here? Fred Astaire, whatever his virtues, was hardly a top singer [tho a most attractive one at that]; but 'A Couple Of Swells' from 'Easter Parade', his duet with Judy Garland, would probably be my choice of best-ever musical number in a film: even more than the two brilliant ones from 'Singing In The Rain', 'Make Em Laugh' & the title number.

Think that needs a new thread. Watch this space.
