“There’s always the bitter disappointment, if, for any reason, the electric spoons don’t work,” laughs drummer and cutlery aficionado Sam Spoons, percussionist with, arguably, the silliest band in the world – Three Bonzos and a Piano.

“Of course anything can not work. That’s all part of it.”

Speaking ahead of Sunday’s [February 5] gig at Putney’s Half Moon, the 69-year-old says he still loves getting up on stage and is looking forward to playing some new songs from the band’s forthcoming album – with the working title Bum Notes.

“We’re still trying to keep the same kind of breadth of music genre, keeping the [anarchic] tradition going as best we can. It’s the usual mix of nonsense.”

The band, which emerged from the ashes of the reformed, but now officially defunct, Bonzo Dog Doo Dah Band, keeps the dada spirit of the old Bonzos’ shows very much alive, with songs such as Jollity Farm, Can Blue Men Sing the Whites? and Monster Mash – featuring Spoons as a mad scientist’s creation who awakes from the lab to play, er, the electric spoons, before collapsing and convulsing amid much smoke and explosions.

The band actually features four members – vocalist and saxophone player Roger Ruskin Spear, Spoons, saxophonist Rodney Slater, and pianist Dave Glasson (he’s “the piano”).

And joining them in the mayhem on the Half Moon stage will be Andy Roberts on guitar.

Described as the missing link between the Goons and Monty Python, the Bonzos featured as the house band on 60s kids’ TV show Do Not Adjust Your Set – which also starred Eric Idle, Michael Palin and Terry Jones.

A typical Bonzos’ show incorporates the lunancy of mechanical robots, electric trouser presses, washboards, and original props, including a mechanical giant hand which extends across the stage – controlled by Spoons from behind his “ad-hoc arrangement of percussion items”.

“I try to avoid doing that too often,” says Spoons.

“I actually forget to do it sometimes but clearly I do enjoy getting the big hand out – and the reaction from the audience.”

Ruskin Spear adds that the new album will be “the usual rubbish”.

“Rodney’s been writing quite a few songs,” he says.

“And I’m going to do a variation of The Intro and the Outro [a classic Bonzos song from their first album Gorilla, namechecking, among many others, the Count Basie Orchestra on triangle and Princess Anne on sousaphone].

It will either be called ‘Err’ or ‘The In-tray and the Out-tray’.”
