From the wiki: “The ballad ‘You’re My World’ was originally recorded in 1963 as ‘Il Mio Mondo’ (‘My World’) by Umberto Bindi, who co-wrote the Italian-language version with Gino Paoli. Although the original Italian version was not a hit, even in Italy, the song came to the attention of UK record producer George Martin who commissioned an English-language version to be recorded by his protégée Cilla Black (‘Anyone Who Had a Heart’, ‘Alfie‘, ‘Love of the Loved‘). Black’s second consecutive #1 hit in the UK, ‘You’re My World’ would be the first track by Black to be released in the US. Peaking at #26 on the Billboard Hot 100 in 1964 (and #4 on the MOR chart), ‘You’re My World’ would be Black’s only US Top 40 hit.
“Daryl Braithwaite of Sherbet remade ‘You’re My World’ as his first solo recording; released in October 1974, it spent the first three weeks of 1975 at #1 on the Australian chart.
“For Helen Reddy in 1977, ‘You’re My World’ marked a return into the Billboard Top 20 for the first time since 1975. Released as a promotional single from her album Ear Candy, the song also tied with Reddy’s signature #1 hit ‘I am Woman’ as the singer’s longest-running Hot 100 hit – nearly 20 weeks on the chart. Ritchie Blackmore has been credited with playing guitar on Reddy’s recording. (Deep Purple, the group Blackmore had fronted, had been managed by Jeff Wald who in 1977 was Helen Reddy’s manager and husband.)
“The potential for further international success (beyond Canada) for Reddy’s version of ‘You’re My World’ was narrowed by the concurrent release of a remake by UK pop group Guys ‘n’ Dolls which was a #1 hit in the Netherlands and Flemish Belgium: although the Guys ‘n’ Dolls version was unsuccessful in the British Isles its release there did cause Capitol UK to make Ear Candy‘s lead single the track ‘Long Distance Love’ with ‘You’re My World’ as the B-side.
“It was reported, after Cilla Black’s passing in 2015, that when the hearse bearing Black’s body arrived at St Mary’s Church, Woolton for her funeral mass, ‘hundreds of fans broke into singing ‘You’re My World”. Black’s grave marker beneath the headstone on her burial plot in Allerton Cemetery is inscribed with the second and third stanzas of ‘You’re My World’. In 2017, a bronze statue of Cilla Black was unveiled on Mathew Street in Liverpool outside the entrance of the Cavern Club where Black was discovered. Black is represented standing on an oversize depiction of a 45″ single copy of ‘You’re My World’.”
