Deep Night - What's New
I believe Deep Night was written by Rudy Vallee, who my great-aunt Marion knew as a boy in Westbrook, Maine. She said he was a "nice boy". Of course he was already quite elderly at the time. At any rate, he was the one who made the song a hit.
Betty Carter takes Deep Night places he probably never imagined it going, a good example of jazz improvisation as composition. Her work with the bassist, Curtis Lundy, I believe , is quite wonderful.
