The late singer and TV star reportedly held meetings with senior figures in the theatre industry prior to her death on 1 August (15) and granted permission for her tale to be depicted on the stage.

Interest in Black's life was rekindled a year before her passing by a 2014 TV drama about her life called Cilla, starring Sheridan Smith in the title role.

A source tells Britain's The Sun newspaper, "Cilla had a meeting with producers interested in turning her life story into a musical. She had actually granted them permission but it wasn't the right time. Now people are swarming around the rights.

"She led an incredible life both professionally and personally. If done in the right way it would be a huge hit and sell out every night."

Black's family and friends will gather in her hometown of Liverpool, England to remember her at a funeral service on Thursday (20Aug15). She died aged 72 after suffering a fall at her home in Spain.
