The current edition of 27-year-old spoof institution “Forbidden Broadway” will be the last — at least for now.

Creator Gerard Alessandrini announced that after “Forbidden Broadway Goes to Rehab” shutters Jan. 15, “Forbidden Broadway” will take what’s to be at least an extended break from Gotham, although the show plans to tour the country after that.

Alessandrini hopes the property will return to Gotham down the line, though whether and when it happens has yet to be firmed up. He cited the “changing of the artistic climate on Broadway” as the impetus for the downtime.

The scribe-helmer has written all 18 editions of the show (which has seen 9,000 perfs). He directs “Goes to Rehab,” which mocks recent Rialto outings including “In the Heights” and “South Pacific,” with Phillip George.

The original edition of “Forbidden Broadway” preemed in 1982 at Palsson’s Supper Club. “Forbidden Broadway Goes to Rehab,” currently in previews at Off Broadway’s 47th Street Theater, opens Sept. 17.
