Lewis Schaffer Is Free Until Famous...even if you do have to pay a tenner to get in. It’s money well spent however, for the veteran comic is on fire right now. The New Yorker killed it at Edinburgh Fringe with his trademark brand of edgy humour, and now he’s set to do it all over again in London. Lewis Schaffer in full flow is a wonderful sight to behold. Watch him and weep tears of laughter. Over 16 only. Running time: 1 hour. Tickets include free access to the Museum of Comedy.
