The national tour of Matilda has brought its naughty hijinks to Los Angeles, and Tony-nominated composer and lyricist Tim Minchin stopped by Conan recently to perform a bit of the show himself. Take a look as he, along with the tour’s three pint-sized headliners Mabel Tyler, Gabby Gutierrez and Mia Sinclair Jenness sing “When I Grow Up.” Minchin, whose next musical project is an adapation of Groundhog Day, discussed splitting the difference between a show like Matilda and his more racy material: “If you back over your hamster in your car or if you’re writing a song about bigotry, swearing’s appropriate, but it’s not necessarily appropriate in a family musical.” So grab some sweets and watch the clips below (after your cartoons, of course). You can catch Matilda on the Great White Way at the Shubert Theatre and in various cities across the U.S.
