On last night’s The Tonight Show Starring Jimmy Fallon, host Jimmy Fallon and the show’s house band The Roots got together for another one of their “Classroom Instruments” performances. This time around, they were joined by Tony Award-winning performer Idina Menzel, or as the whole world knows her now thanks to John Travolta — Adele Dazeem.

For this installment of Classroom Instruments, the gang did a special rendition of “Let It Go,” from Disney’s Frozen, which Menzel sings in the film.
