Matt Lucas took on the role of genial quizmaster at a fundraiser in Elstree on Sunday in aid of the Alan Senitt Trust and Northwick Park hospital radio station.
The Little Britain star's appearance helped to attract a 300 capacity crowd. He is a patron of the trust, set up by the Senitt family in memory of the young Jewish activist and interfaith worker who was murdered in America four years ago. Mr Lucas also knows the Senitts well from his younger days at Edgware Reform Synagogue.
He spoke of the loss felt by the community at Mr Senitt's passing.
Raffle and auction prizes included a framed poster from the Alice in Wonderland film in which Lucas appears, signed by the director, Tim Burton. The quiz raised £5,000.
