Channel 4s Big Fat Quiz of Everything tests celebrities knowledge on various subjects including history, geography, films, television, music, science and technology.
A spin off from The Big Fat Quiz of the Year, the competition first took place in 2015.
2017 showed the quiz on Friday night, hosted by Jimmy Carr, with contestants Jonathan Ross, David Walliams, Katherine Ryan, Aisling Bea, Noel Fielding and Richard Ayoade.
The contestants are often given interactive challenges and this year was no different.
The London Philharmonic Choir appeared and sang three popular songs for the contestants, who then had to guess what they were.
Can you name them?
