Cannes

At a Cannes Film Festival during the 1970s Cilla joined George Harrison, Ringo Starr, and glam-rock pop star Marc Bolan to attend a screening of the John Lennon-Yoko Ono experimental film Erection. She also holidayed with them on this trip aboard a yacht chartered by Ringo. "Photograph" was written on this trip - originally intended for Black to record - but Starr decided to record it himself. George Harrison also wrote two songs for Cilla - "The Light That Has Lighted The World" and "I'll Still Love You (When Every Song Is Sung)". The latter she recorded in 1974, but it was not heard publicly until 2003, when it surfaced on a retrospective collection entitled "The Best of 1963-78".

Cilla at the BBC

On 6th February 1968 the Three Beatles worked 12 hours at EMI 2:30pm-2am on the "Inner Light" and "Lady Madonna" only taking a break from 8pm to 9pm to watch Ringo on the first episode of Cilla Black’s show Cilla. Ringo is seen on this show with Peter Brough with his puppet Archie Andrews and participated in two sketches, first acting as a ventriloquist with Cilla singing "Nellie Dean". Finally he duetted with Cilla on “Do You Like Me?” and on “Act Naturally”.

Paul McCartney wrote the theme tune to her BBC series - "Step Inside Love". The author and critic Johnny Rogan noted in 1997; "for Paul McCartney to write a song for someone - at that time - was a tremendous privilege, and he wouldn't have done it but for his belief that Cilla Black was an important artist."

The earlier series of Cilla became a phenomenon. Guests included Tom Jones, Mary Hopkin, Donovan, Georgie Fame and Henry Mancini.
