Well, seeing that somebody mentioned Rogers and Hammerstein songs, I'm surprised you haven't remembered "My Favorite Things" and "I Whistle A Happy Tune." And while we're on a Broadway kick, how about "Tomorrow" and "Put On a Happy Face"?

Another fun one is "Be Optimistic" from the Shirley Temple film Little Miss Broadway. Another good one of hers was "This Is A Happy Little Ditty" from Just Around the Corner.

In another genre, the Sons of the Pioneers did a great toe-tapping number called "Yippi-Yi Your Troubles Away."
