The song "The Boys Are Back" from High School Musical 3: Senior Year as sung/told by the two Little Einsteins boys Leo and Quincy.
DISCLAIMERS:
I own nothing.
Show (C) Disney Junior
Song (C) Walt Disney Records.
If you love the 2007 musical film Hairspray, you'll love this crossover of the Little Einsteins singing the song. This features the Muppet Show's Kermit the Frog and Miss Piggy in it too.
Enjoy.
