What is a sing-along bar?

A sing-along bar is a bar or other establishment that features live music, typically with a piano player or band, and encourages customers to sing along. Sing-along bars often have a relaxed atmosphere and a casual dress code, and they may provide songbooks or lyrics on screens for customers to follow. Some sing-along bars also host themed nights, such as '80s night or country music night, and may feature special guest performers or karaoke.
