The Dapper Dans are a barbershop quartet that performs at Disneyland in Anaheim, California (since 1959), at the Magic Kingdom at the Walt Disney World Resort (since 1971), and at Hong Kong Disneyland in Lantau Island, Hong Kong (from 2005 to 2008). A quartet (from the UK) also performed at Disneyland Paris from the opening in 1992 until 1995 and were known as the Mainstreet Quartet.
While the group usually performs as a quartet, they actually have up to twelve singers at each park, plus occasional substitutes. This allows them to have multiple quartets performing separately or to combine and form a larger ensemble. Membership has changed over the years as various singers have retired or died and new ones have been brought in to succeed them. Several of the Dapper Dans are members of the Barbershop Harmony Society.
Visitors can be serenaded by the Dans at the Magic Kingdom in Florida while having their hair cut in a real, working barbershop on Main Street there. The Dans at Hong Kong Disneyland stroll up and down Main Street from Town Square. The Dans at Disneyland can be seen on their Schwinn custom four-seater bicycle (commissioned by Walt Disney himself) and in various locations around Main Street.
