The Bonzo Dog Band (also known as The Bonzo Dog Doo-Dah Band, The Bonzo Dog Dada Band and, colloquially, as The Bonzos) are a band created by a group of British art-school denizens of the 1960s. Combining elements of music hall, trad jazz, psychedelic rock, and avant-garde art, the Bonzos came to the attention of a broader British public through a children’s television programme, Do Not Adjust Your Set. After three reunions (in 1972, 1988 and 2006) a conflict arose with Neil Innes, which led to the spinoff Three Bonzos And A Piano.

The core members of the group for most of the band’s career were:
* Vivian Stanshall (1943–1995): trumpet, lead vocals
* Neil Innes (1944 - 2019): piano, guitar, lead vocals
* Rodney Rhino Desborough Slater (b. 1944): saxophone
* Roger Ruskin Spear (b. 1943): tenor sax and various contraptions
* Legs Larry Smith (b. 1944): drums

However, the band’s onstage line-up varied, sometimes on a weekly basis, and they also invited a number of guest musicians into the recording studio. Additional members of various duration include: Vernon Dudley Bohay-Nowell, Martin Sam Spoons Ash, Happy Wally Wilks, Tom Parkinson, Chris Jennings, Claude Abbo, Trevor Brown, Tom Hedge, Eric Idle, Eric Clapton, Elton John, Paul McCartney, Leon Williams, John Parry, Raymond Lewitt, Sydney Big Sid Nicholls, James Jim Strobes Chambers, Bob Kerr, Dave Clague, Joel Druckman, Borneo Fred Munt, Chalky Chalkey, Dennis Cowan, Aynsley Dunbar, Jim Capaldi, Anthony ’Bubs’ White, Andy Roberts, Dave Richards, Pete Currie, Dick Parry, Hughie Flint and Glen Colson.

Stanshall and Innes were the band’s principal songwriters. After the band’s demise, both became founding members of Grimms along with the members of The Scaffold.
