One drunken karaoke moment in the late ’90s changed the course of Dan Finnerty’s life. On impulse, he delivered a rendition of Helen Reddy’s signature song “I Am Woman” to the crowd in a bar and was an instant hit. Within a few years, he had an act that sold out clubs in Hollywood and attracted celebrities and filmmakers, including director Todd Phillips. The Dan Band became the best-known wedding band in the movies, appearing in Phillips’ Old School and Starsky & Hutch while Finnerty starred in films such as The Terminal and Rock of Ages.

He also gained visibility as a comedy correspondent for The Tonight Show with Jay Leno and fronted The Dan Band for a Bravo special in 2006. Television audiences were able to see what wowed Mark McGrath and Pam Anderson on the club circuit when Finnerty and two bespectacled backup singers blazed through a set of songs made famous by women. “You Oughta Know,” “No Scrubs,” “Hold On” and “Genie in a Bottle” are just a sampling of karaoke favorites that Finnerty and company bust out complicated choreography to while making audience members laugh at well-placed f-bombs or cry due to the emotional triggering of the song itself.
