"Babes in Arms": I Wish I Were in Love Again, title song
"Pal Joey": Our Little Den of Iniquity, Zip
"I Married an Angel": Did You Ever Get Stung, At the Roxy Music Hall, I'll Tell the Man in the Street, Spring Is Here, How to Win Friends and Influence People
"Dearest Enemy" (thanks to Elmore): Where the Hudson River Flows, The Hermits, Here in My Arms, Bye and Bye
