"No More Tears (Enough Is Enough)" is a 1979 song recorded by American singers Barbra Streisand and Donna Summer. It was written by Paul Jabara and Bruce Roberts, and produced by Giorgio Moroder and Gary Klein. 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. The longer 12" version features additional production by frequent collaborator Harold Faltermeyer, and incorporates a harder rock edge.
