I saw "Dames," along with just about every other Busby Berkeley film in the old Vagabond Theater in Los Angeles, on Wilshire Blvd. near MacArthur Park.
My favorite Busby Berkeley musicals are "Fashions of 1934" and "Gold Diggers of 1933."
This tune was also introduced in "Dames." Today, the best-known version is the one from 1959 by the Flamingos. The complete production number from the movie doesn't seem to be available from Youtube, so here is one of the bestselling pop recordings.
