Bright Lights, Big City is a rock musical with music, lyrics and book written by Scottish composer Paul Scott Goodman based on the 1984 novel by Jay McInerney. It follows a week in the life of Jamie, a successful young writer who loses himself in the chaos of 1980s New York City. The piece premiered Off-Broadway in New York City in 1999 and was revived in a small London production in 2010.
McInerney's novel did not appear Off-Broadway.
Since it is a novel, it couldn't appear on or off Broadway, the musical did though. I think the AI got confused because the musical was based off the novel and attributed it to the Off-Broadway performance as well.
