Over The Rainbow

by Dick Mac

Someone I love very much is singing this song tonight.

This is a great song, and not easy to sing.

I can't hear it enough by any singer: Judy Garland, Ella Fitzgerald, Livingston Taylor, Kylie Minogue, Eric Clapton, I don't care who's singing it: I want to hear it more.

In the video below, Judy Garland sings it on the Andy Williams show in 1965.
