Singer Tom Jones is to try his hand at comedy at charity concert in aid of Amnesty International.

The legendary crooner, best known for hits like It's Not Unusual and Green Green Grass Of Home, will be one of a host of performers in an Amnesty International benefit concert organised by comedian and actor Eddie Izzard.

Comedian Harry Enfield is also lined up to sing at the event, We Know Where You Live - Live! at Wembley Arena in London on 3 June.

Along with Jones and Enfield, the roster includes Harry Hill, Richard Blackwood and Trigger Happy TV creator Dom Joly.

Mercury Music Prize winner Badly Drawn Boy is also performing.

A spokeswoman said: "All the acts will be doing wacky things. Everybody's going to be doing things they're not expected to so we're expecting Tom Jones to do comedy and Harry Enfield might sing.

"It's all going to be unexpected and some of the acts will be working with each other."

Eddie Izzard: artistic director of the charity event

The cast of BBC Two hit comedy Goodness Gracious Me are believed to be working on an interpretation of a Monty Python sketch.

This year's Amnesty International event - a regular fixture since 1961 - is particularly significant because Amnesty International is celebrating its 40th anniversary.

The last Amnesty International benefit event was the Secret Policeman's Ball in 1991.

John Cleese, artistic director of most of the previous Policemen's Balls, has relinquished his duties in favour of Eddie Izzard.
