This will sound familiar: The comedian Sebastian Maniscalco has added yet another show to his weekend run in April at the Palace Theatre. Maniscalco, whose surging career included four soldout performances at the 18,000-seat Madison Square Garden in New York City last year, will do his stand-up routine at the 2,800-seat Palace at 5 p.m.

Sunday, April 5. The other five Palace performances — at 7 and 9:30 p.m. April 3 and 4, and 8 p.m. April 5 — are essentially sold out, with extremely limited single seats remaining, said Billy Piskutz, acting executive director of the theater.
