She first topped the charts with Anyone Who Had A Heart more than 50 years ago.
Now, a new disco single by singer and TV presenter Cilla Black has surfaced “like a time machine”, and is set to be released five years after her death.
Love song You’re Sensational, a previously unheard track, will be out on Valentine’s Day, a statement posted on the late singer’s official website said.
Recorded in the 1970s as a follow-up to her Top 10 hit song Something Tells Me, the statement says the tapes then went missing, only to be found in an archive storage unit decades later.
Her eldest son and former manager Robert Willis said that before the discovery, he had thought all her recorded music had been released.
“I thought we had released everything there was to release,” he said. “So it was a real joy to find a complete unreleased track by my mother from the early 1970s.
“I think the fans will really enjoy hearing it for the first time as much as I did.”
The single has been remixed by Dutch music producer Matt Pop.
He said: “Now that Cilla is sadly not with us anymore, to have this surface like a time machine from the disco era was quite magical.
“There’s no two ways about it: it’s disco!”
Black, who hosted shows including Blind Date, Cilla and Surprise Surprise, died at her home in Spain in 2015, after suffering a stroke.
In 2014, the story of her early years was turned into a mini-series starring Sheridan Smith, and was later adapted into a musical in 2017.
The new single will be made available for digital download by Warner Music on 14 February.
