When TV super couple Megan Mullally and Nick Offerman team up — you better be ready to listen.

Broadway @ the Performing Arts Center announced its 2016 summer season in Martha's Vineyard and includes a one-night-only performance of their comedy-variety show, “Summer of 69: No Apostrophe” on Aug. 29. The show, which originally debuted in 2014, is a humorous depiction of their real life relationship as middle age celebrities in love — in fact, the most in love of anyone who has ever been in love.

As Offerman told the Washington Post back in June 2014 when the show opened in D.C., “It’s about the greatest love relationship of all time… according to legends that we’ve heard, we might be. Really, we’re just reacting to the claim. We just thought we would compile a 90-minute celebration of why the world would have come up with such a theory.” The show is interlaced with true and false tidbits about their lives together — “That’ll be part of the fun in this, trying to figure out which stories and skits are true and which are false,” Mullally added — inter-spliced with songs and “light petting.” Naturally.
