Every now and again Jimmy Fallon and The Roots get together with musicians and cover popular songs with them. Jimmy and his Tonight Show house band broke out the classroom instruments most recently with the wickedly talented Idina Menzel to perform a fun version of her big, Oscar-winning Frozen tune “Let It Go.” Enjoy!

Bonus clip! Jump after the break to watch my favorite “Let It Go” cover by Nigerian singer Alex Boye featuring a very talented 11-year-old Lexi Walker and The One Voice Children’s Choir.
