Jimmy Fallon, Meghan Trainor & The Roots Sing “All About That Bass” (w/ Classroom Instruments)

I can’t tell you how much I love Meghan Trainor’s song “All About That Bass.” If you haven’t heard it…here it is.

Meghan stopped by by the Tonight Show Music Room to perform “All About That Bass” with The Roots and Jimmy Fallon and classroom instruments.

So much fun!
