Jimmy Fallon and The Roots sing with Adele during the Music Room bit on The Tonight Show Starring Jimmy Fallon on Nov. 24, 2015.

Did you catch Adele giving fans a whole new version of her megahit "Hello" to obsess over? Tuesday night (Nov. 25) Jimmy Fallon premiered the latest version of his Classroom Instruments bit, and -- to the surprise of no one -- Adele, Fallon, and The Roots hit this version out of the park.

Best 'Tonight Show' Music Moments of the Year

We rounded up five of our favorite Classroom Instrument segments (from both Tonight Show and Late Night With Jimmy Fallon) below for your enjoyment. 

1. "Hello"
