The musician and comedian Neil Innes has died at the age of 75, his agent has confirmed.
The agent, Nigel Morton, said the death was unexpected and that Innes had not been ill.
Innes first became famous as a member of the humorous art-pop group the Bonzo Dog Doo-Dah Band and was known for his frequent collaborations with Monty Python comedy troupe.

His work with the Pythons – including writing music for albums including Monty Python's Previous Record and The Monty Python Matching Tie and Handkerchief – led him to be known as the “Seventh Python”, also the name of the 2008 musical documentary about his career.
Innes penned original songs for the film Monty Python and the Holy Grail including Knights of the Round Table and Sir Robin, as well as acting in the picture in minor roles.
Innes went on to have a small role in the troupe’s 1979 film Life of Brian.
He was also only one of two non-Pythons to have been credited as a writer for the group’s TV show, the other being future Hitchhiker’s Guide To The Galaxy author Douglas Adams.
Innes’s group the Bonzo Dog Doo-Dah Band first achieved public prominence with a performance in The Beatles’ Magical Mystery Tour film in 1967.
Their song I'm The Urban Spaceman – produced by Paul McCartney – reached No 5 in 1968 and earned Innes an Ivor Novello award.
Later he was also a member of the parody band The Rutles, the subject of Python Eric Idle’s Beatles-spoofing mockumentary All You Need Is Cash.
Tributes have poured in for Innes, with actor Mark Gatiss tweeting: "Neil Innes has gone. As a Python-obsessed teen I saw him at Darlington Arts Centre & missed my bus home to catch his brilliance. I used to record ‘The Innes Book of Records’ on C-60s & marvel at his talent. I still hum ‘I like Cezanne, says Anne’. Sweet dreams, sweet idiot."

Comedian and actor Diane Morgan said: "Fairwell Neil Innes. One of the nicest people I’ve ever met and a towering talent."
While writer and director Edgar Wright posted: "If it's true that the great Neil Innes had sadly passed away, please let me raise a glass to the man. Forever a fan of The Bonzo Dog Doo Dah Band. Allow me to share a favourite clip of them in action (with a bonkers Innes guitar solo too). RIP Neil."
