Graham Norton, Davina McCall, Jonathan Ross and David Tennant are among the hosts of Comic Relief – Funny For Money

This is must-see TV at its finest as Comic Relief takes over BBC One for a whole night of comedy gold in a one-off extravaganza of top telly treats.

An amazing bounty of TV beauties will guide viewers through the big night, with hosts including David Tennant, Davina McCall, Fern Britton, Claudia Winkleman, Jonathan Ross, Alan Carr and Graham Norton.

Comedy sketches come from Little Britain and Ricky Gervais, while Harry Enfield and Paul Whitehouse pitch their wares to the Dragons' Den judges.

There'll be tears of both laughter and sadness as French And Saunders perform their last sketch, and old friends and new flames join the comedy queens in a toe-tapping, show-stopping unforgettable farewell.

Gavin And Stacey's James Corden (Smithy) imparts his wisdom to the England football squad and the Outnumbered family embraces all that Red Nose Day has to offer.

Throughout the night, Davina McCall, Lenny Henry, Paul O'Grady and Ant & Dec report back on how the money raised is hard at work and changing lives here in the UK and in Africa.

Viewers can also tune in to see the conclusion of Comic Relief Does The Apprentice and see which of the celebrity candidates feel the wrath of Sir Alan Sugar and hear the immortal words: "You're fired!"

There are more special moments from Let's Dance For Comic Relief, a one-off Sarah Jane Adventures sketch, featuring national treasure Ronnie Corbett, and a unique collaboration between double-acts Armstrong & Miller and Mitchell And Webb.

Also in the studio, performing live for the nation, are Britain's biggest boy band – Take That – as well as Franz Ferdinand and girl band The Saturdays, who perform one of this year's Red Nose Day singles, Just Can't Get Enough.

Gavin And Stacey stars Rob Brydon and Ruth Jones (aka Bryn and Nessa) also perform their own delightful version of (Barry) Islands In The Stream, live in the studio.

On BBC Two at 10pm, Comic Relief spreads the music love with a special one-off edition of Top Of The Pops. Fearne Cotton and Reggie Yates are joined by a host of comics to present an incredible live show, including performances from Oasis, U2 and, once again, Rob Brydon and Ruth Jones, giving another rendition of their Comic Relief single.

James Corden and Mathew Horne bring up the rear in the wee hours as they guide viewers through some of the more risky and rude moments from Red Nose Days past.
