Here are some of the best classical music pranks ever to have been pulled - from violin smashes to choirs singing on helium.

Teacher smashes pupil's violin

The Royal Albert Hall gets a Beatles in its bonnet
The Royal Albert Hall claimed to have "discovered" a letter signed by someone called 'Ernest O'Folliper' showing the executive at the time was furious that the building had been name-checked by The Beatles.
But the best?
Well, call us immodest, but we ran a pretty great prank ourselves this April Fool's Day, since you ask, when Classic FM presenter John Suchet was replaced by his brother – and actor extraordinaire – David Suchet.
