Jimmy Fallon Challenges Adam Levine to a Game of Musical Impressions [VIDEO]

Who knew that Adam Levine of Maroon 5 could bring out his inner Frank Sinatra or Michael Jackson?

Jimmy Fallon challenged Adam to a friendly game of 'Random Musical Impressions' in which they had to impersonate whatever artist and song the wheel landed.  It was quite random, for Adam ended up singing 'Head, Shoulders, Knees, and Toes' in his Frank Sinatra voice.  He also ended up singing the Sesame Street theme song in his Michael Jackson voice!
