B.o.B + O.A.R. Perform ‘Champions’ on ‘Tonight Show With Jay Leno’
B.o.B visited the 'Tonight Show With Jay Leno' on Tuesday, but instead of promoting one of the songs from his brand-new 'Strange Clouds' album, the rapper invited veteran rock band O.A.R. to perform 'Champions,' their collaboration for Duracell's 2012 Olympics Games campaign.
