In the movie what women want with mel gibson what song was mel gibson singing to himself?

Question

thank you thats what i wanted

Answer 1

When he was dancing around the house? "I Won't Dance" by Frank Sinatra was that one. When he was walking around town at the beginning? I think it was "Mack the Knife" by Bobby Darin (which was playing in the background, so I may be confused). If not those, can you be more specific?
