Robbie Williams surprised onlookers on Tuesday (December 2) by performing an unexpected slot in London.

The singer teamed up with Michael McIntyre's Very Christmassy Christmas Show to perform from the balcony of the Punch and Judy pub in Covent Garden.

He ran through tracks like 'I Wish It Could Be Christmas Every Day' and other non-festive songs from his back catalogue.

There was fake snow on offer too as Williams got into the festive spirit.

The singer meanwhile released his surprise record 'Under The Radar' on Monday (December 1).

The album, which is exclusively available from Williams' website, features tracks that never made it onto his previous records.
