and it was the name of a very successful, but light, musical theatre piece written by Dorothy Reynolds and Julian Slade in 1954.

"Maybe I'll wait till I'm too late,
But I shall have waited for one good reason.
Here in the sun, the sun, the sun,
I might be in love by the end of the season."

"We mustn't look back. No, we mustn't look back.
Whatever our memories are.
We mustn't say these were our happiest days,
But our happiest days so far."
