The comedian brings his 'Out of My Head' stage show, which includes sketches and music with his wife Suki Webster and colleagues Richard Vranch and Lee Simpson, to London's Vaudeville Theatre next week.
"My main motivation for it was that when I used to do stand-up I'd be one of four people on a bill, and it was a nice social thing," the Have I Got News For You regular told the Evening Standard.
"When I did my last solo tour I was sitting in the dressing room during the interval listening to the bustling crowd on the intercom with a cup of tea on my own, thinking, 'I've got to go back and listen to myself talking for another 45 minutes'."
Merton added: "I realised I'm a team player. Performing with others is not the icing on the cake, it is the cake. If it was two hours on my own, I'd probably lose interest."
