The movie included more than those two songs. Also featured were "Little Girl Blue," "The Circus Is On Parade," and "Over and Over" (each a classic). Another Rodgers & Hart song "Why Can't I" (from SPRING IS HERE" was interpolated.
My apologies. You are correct. It's been many years since I've seen the Jumbo film. It does feature 5 songs from the Broadway score plus additional interpolated Rodgers & Hart songs and a new number by Roger Edens. I was basing the statement in my earlier post on the Wikipedia article about the film which said it included only 2 of the Broadway songs. I should have checked the song list from the soundtrack recording, available on Amazon. The film is delightful.
