During our 2012 visit to the Magic Kingdom we were able to catch one of the street performances by Dapper Dans barbershop quartet. Found on Mainstreet U.S.A. the quartet does short five to ten minute shows, and if one of the park staff is to believed, are used to help alleviate traffic in the park so specific areas don’t become inundated with visitors; which given the number of people that can be there some days could easily be accomplished. This is a short cut of the video and runs approximately 2 1/2 minutes long.
