Dueling Pianos
Dueling pianos (also known simply as "sing-along") is a form of entertainment, usually on stage with two grand pianos, each played by a professional player who sings and entertains; humor and audience participation are prevalent. Usually these types of piano bars have substantial sound systems, and most of the songs performed are rock and roll, "classic rock", Top 40, R&B, or country, played primarily by request. The modern format originated in late 1986 at Alley Cats in Dallas, Texas, and was based on the old-style dueling pianos still found at Pat O'Brien's Bar in New Orleans.
