“It’s Only a Paper Moon” was written in 1933 by one Harold Arlen. He composed it for a really crappy Broadway play called The Great Magoo. The play had such poor reception that the song fell away into oblivion. But its lasting fame came from recordings by popular artists covering it during the World War II era – people like Ella Fitzgerald and Nat King Cole. You can find the download on the Jazz/Swing list on the right.
If you want to do the long legato intro just shoot me an email and I’ll send that version to you.
