"You're My World" is a cover of Italian ballad originally recorded in 1963 as "Il mio mondo" by Umberto Bindi, who co-wrote the original version with Gino Paoli. Subsequently, an English version was commissioned, and the lyrics were written by Carl Sigman as "You're My World". The song reached No. 1 in Australia (twice), Belgium, Mexico, Netherlands, South Africa and United Kingdom in recordings by Cilla Black, Daryl Braithwaite, Guys 'n' Dolls and Helen Reddy. Black's and Reddy's versions reached the US Top 40 in 1964 and 1977, respectively. The song also reached No. 1 in France and Spain in the respective translations "Ce monde" and "Mi Mundo", both sung by Richard Anthony.

Priscilla Maria Veronica White, better known as Cilla Black, was an English singer and television presenter.
