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.
In the Magic Kingdom, Disney World, the Dapper Dans perform nine sets a day, seven days a week. They can be found on the horse-drawn trolley in the morning, and all over Main Street USA during the afternoon. At 5pm, the Dans join the Main Street Philharmonic and the Magic Kingdom Security Color Guard for the Flag Retreat Ceremony.
Another unique part of Dapper Dans lore is the fact that they use Deagan Organ Chimes as part of the act. Each of the eight chimes has three octaves of a single note, comprising a C scale. The Organ Chimes were made by the J.C. Deagan Company in Chicago, Illinois, around 1901.
The quartet at Disneyland as of 2010 normally consists of Jon Schoenherz (lead), Drew Tablak (tenor), Eulis Kay (baritone) and Jim Campbell (bass) with substitutions by Frank Romeo (bass), Isaac James (lead), Jim Graft (bass), Gabriel Oliva (bass-lead), Joe Sark, John Helms (lead), Mark Donahue (lead), Jason Currie (baritone), Allen Everman (baritone), Nathan Shrake (tenor), Peter Chudyba (tenor), Jeremy Kocal (tenor), David Marchesano (lead), Manuel Rodriguez-Ruiz (bass).
