"Let's Live for Today" is a song written by David "Shel" Shapiro and Italian lyricist Mogol, with additional English lyrics provided by Michael Julien. It was first recorded, with Italian lyrics, under the title of "Piangi con me" by the English band the Rokes in 1966. Later, when "Piangi con me" was to be released in the United Kingdom, publisher Dick James Music requested that staff writer Julien compose English lyrics for the song. Julien composed new lyrics, rather than translating from the Italian, and it was his input that transformed "Piangi con me" into "Let's Live for Today".

The Rokes were a pop rock band formed in 1963 in Italy by English expatriates. Their most successful songs included "Piangi con Me", the original version of "Let's Live for Today", a US hit when re-recorded by The Grass Roots; and "Che Colpa Abbiamo Noi", an Italian language version of "Cheryl's Going Home" by Bob Lind.
