This kid pleases an unsuspecting crowd with an acoustic version of Usher’s RnB hit, Yeah! Using a loop pedal, he sets the rhythm with a few layer parts to get the beat going and as soon as he starts busting out the lyrics, the crowd goes wild! It seemed like he almost cracked up laughing but he has obviously well rehearsed and kep the song going well. Great job on the song, and good for a giggle or two as well.
