The credits on the back cover read: "All tracks featuring Frankie Valli, John Travolta and Olivia Newton John". This is not true. In reality, Frankie, John and Olivia only appear on tracks 1, 2, and 4. Track 3, as indicated below, is performed by John Travolta, Olivia Newton-John and The Cast Of Grease. "We Go Together" is essentially this single's B-side.
