"Seasons in the Sun" was a worldwide hit song for Terry Jacks in 1974. It was first released in the United States and Canada early in the year, and rose to number one in America by March 2. The song had been done by English band The Fortunes in 1968, and by Pearls Before Swine in 1970/71.

The song was based on a song called "Le Moribond" ("The Dying Man") by Jacques Brel. Brel's song was translated into English by poet Rod McKuen, and McKuen's English version was recorded by Bob Shane of the Kingston Trio, which did not sell.
