From cinemareview.com:
When the filmmakers told Higgins they needed someone familiar with a capella singing, Higgins didn’t flinch. “I’m actually not an a cappella person,” he confesses. “I used to sing with a group a long time ago. But I said, ‘You know what? I can write arrangements. I can rehearse a group.’ Me and my big mouth.”
Taking him up on his offer, the filmmakers gave Higgins the tasks of preparing music, writing arrangements and convening/rehearsing a vocal group for their scenes. “Michael was put in charge of rallying this group, and he ran with it,” says Lavender. “He brought together this tremendous group of extremely talented singers from L.A., New York and Chicago.”
In the film, which premieres Friday, June 2, the onscreen group, known as "The Tone Rangers", gives new life to the classic disco hit "Boogie Nights", while John Michaels Higgins does some Kung Fu Fighting on an unsuspecting Vince Vaughan. A huge concert ending of the Tone Rangers onstage doing the "Willam Tell Overture" and "The Rainbow Connection" was cut from the film, but will be, sources tell us, available on the DVD.
