The song was recorded for Streisand's Wet album and also as a new track for Summer's compilation double album On the Radio: Greatest Hits Volumes I & II. The full-length version was found on Streisand's album, while a longer 11-minute edit (the 12" version) was featured on Summer's album.
Listen here to the original and various renditions.
At the very end. The last two audios. Barbara speaking from her memoir on Donna and her experience in recording. Also, the demo version from 1979. Magnificent history.
