Watch Jimmy Fallon Challenge Adam Levine to a Children’s Song Sing-Off

Jimmy Fallon challenged Maroon 5 frontman, Adam Levine, to a sing-off involving children’s songs Tuesday on The Tonight Show.

The game involved imitating famous singers as if they were singing well-known children’s songs. Levine belted out his best Sinatra voice, singing the song, “Head, Shoulders, Knees and Toes,” while Fallon did a not-so-recognizable imitation of Iggy Azalea singing “Old Macdonald” to the tune of her hit song, “Fancy.”

Levine and the rest of the band released their newest record, “V,” on Tuesday ahead of a world tour in 2015.
