Watch: Idina Menzel sings ‘Let It Go’ with Jimmy Fallon, the Roots

There’s no question she was playing to a bigger audience Sunday night at the Academy Awards.

But Idina Menzel appeared to be having way more fun Monday when she dropped by “The Tonight Show� to jam with Jimmy Fallon and the Roots.

As she did on the Oscars (where John Travolta notoriously mangled her name in his introduction), the singer performed “Let It Go,� the sweeping power ballad from Disney’s “Frozen� that was named best original song Sunday.

Backed by Fallon and his house band on a variety of kid-friendly instruments, though — a setup the host used in his “Late Night� days for appearances by Carly Rae Jepsen and Robin Thicke — Menzel seemed far more relaxed than she did at the Dolby Theatre.

Idina Menzel: 1. Adele Dazeem: 0.
