The song was written by Larry Vincent (music) and Harry Pease (lyrics) in 1964, and sung in that year by Robert Cogoi. Marcel Martel (1976), Marie King (1977) and Carole Laure (1989).
Lucille Starr called it the "French Song."

The lyrics are those I posted 08 Jul 04, from www.paroles.net, but I posted the one with the repetitive last verse by Carole Laure. The date 1989 was for the Laure recording.

"The Last of the Summer Wine," the excellent TV series, is available on DVD; I haven't seen the prequel ("First ...") offered. Is it available?
