Sir Ken Dodd, OBE, is an English comedian, singer-songwriter and actor, known for his unruly hair.
The 90-year-old is famed for his white and blue "tickling stick" and his well-loved catchphrase “How tickled I am!”.
Sir Kenneth Arthur Dodd, OBE was born on November 8 1927 and is currently 90-years-old.
Born in Liverpool, Ken is an English comedian whose work is part of the music hall tradition.
In the 1960s he was as famous as The Beatles in the UK and his version of the song Tears was the UK's third-best-selling single of the 1960s.
His records sold millions worldwide and he continues to tour with The Ken Dodd Happiness Show.
He was knighted in the 2017 New Year Honours for his services to entertainment and charity.
Ken Dodd’s most famous song is a version of Tears, a song written by lyricist Frank Capano and composer Billy Uhr.
It sold over 1.5 million copies and is the 33rd best-selling single of all time in the UK.
The star – who sold millions of records worldwide, also had huge success with The River, Love Is Like A Violin and Promises, to name a few.
His catchphrase is “How tickled I am!”.
A Ken Dodd statue was unveiled on June 11, 2009 in Liverpool Lime Street Railway Station.
It depicts the star in a suit with his trademark “tickle stick”.
Ken Dodd has had two long-term engagements.
His first fiancée, Anita Boutin, died of a brain tumour in 1977 after they had spent 22 years together.
Ken is currently with Anne Jones, a former Bluebell dancer who appears in his shows playing the piano, guitar, flute and singing.
They have been unable to have children.
Ken fell ill with the flu on January 12 and has been in hospital with a severe chest infection that came about as a result.
He has spent nearly a week being cared for by medics.
Liverpool-born Ken was taken by ambulance to a hospital in the city after struggling to breathe.
His wife Anne, 76, has remained at his bedside.
A pal said: “Doddy’s a fighter but flu is very serious for a 90-year-old.
“He was struggling last week and had trouble breathing so an ambulance was called and they’ve decided to keep him in until he’s well enough.”
