Representatives for the production could not immediately comment on the report. The film's original producer Matty Simmons, who is also the executive producer of the stage musical, broke the news to the Lethbridge Herald.
"It just wasn't something we liked," Simmons said of the initial songs by Barenaked Ladies. "We wanted music that would fit the story and the nature of the story and the raucousness of the story. The movie has a personality and the music had to suit that, you know?"
The musical is aiming for a 2014 premiere. Animal House has a book by Michael Mitnick (Sex Lives of Our Parents). Tony Award winner Casey Nicholaw (The Book of Mormon, Elf, Spamalot) has been announced to direct.
