Cilla Black was a favourite in Glasgow's concert halls at the height of her singing career.

She was the last act to perform at the Alhambra Theatre, Glasgow, in 1969. The iconic theatre stood on the corner of Waterloo Street and Wellington Street and was demolished in 1971.

Spanish police confirmed today that the entertainment legend passed away at her home on the Costa del Sol.

They say her death appears to be a result of natural causes.

Singer Sir Cliff Richard said he will miss his "outrageous" friend dearly.

"Some people will always be with us and Cilla is one of those people," he said.

"I will always think of her as outrageous, funny, incredibly gifted but above all full of heart.

"She was a very special person, and I have lost a very wonderful friend, I will miss her dearly. God bless her."

Friend and fellow presenter Christopher Biggins, who starred alongside Cilla in Surprise! Surprise!, described Black as a "national treasure" adding that she will "always be with me".

"It's devastating news, really devastating," he said.

"She was a wonderful friend. She was someone who was a life force, she loved to laugh and loved to enjoy herself.

"She will always be with me. She was a national treasure."

Lord Grade, former executive chairman of ITV, said a once nervous Cilla soon gained a natural confidence in front of the cameras and went on to become an "enduring family favourite".

"A natural, natural performer of the highest quality," he told Sky News.

"One of the all time greats in showbiz.

"She always felt like a friend in your living room when she was on TV. A magical lady.

"She had a huge, huge talent once she got her confidence. She became a national favourite, an enduring family favourite."
