In 1985, Frank Zappa wrote Does Music Belong In Humour? Pluck, with their blend of polished classical music and tomfoolery, would say without doubt that it does.

The trio of musicians play Bach, Vivaldi and Ravel while dancing, fighting, ridiculing each other, miming and generally clowning around - without missing a beat.

The audience participation was very good. At one point, two members were recruited to do the percussion for Stand By Me.

While the woman immediately mastered the scraper, her partner repeatedly failed to play the triangle on the third beat - inadvertently creating one of the most comic moments of the night.

Another funny moment was when members of the trio appeared to become infatuated by individuals in the audience.

Pluck also ran through a history of sound recording, cleverly providing the music themselves to devices such as a gramophone and eight-track cartridge.

However, by combining music and humour, Pluck risk watering down the power of both.

There were a couple of belly-laugh moments but they will never be a comedy act. Equally, beautifully-played music can evoke many more powerful emotions than humour which Pluck do not tap in to.

Yet their charmingly naive sketches are just right for those who want to hear perfectly-executed classical music but want more than a dull recital.

You can imagine them playing at the Queen's birthday as easily as in the Spiegeltent.
