BOSTON – “Defending the Caveman”, the longest running solo play in Broadway history, returns to Boston by popular demand March 5 through 16 at the Stanford Calderwood Pavilion at the Boston Center for the Arts.This popular comedy about the sexes stars Michael Van Osch as the Caveman. Osch has been portraying the “caveman” for more than two years and he said it’s a role he loves.”It’s not just standup,” he said. “We talk to the audience. We take the audience on a journey from prehistoric times. It’s about how the differences between men and women can get us into trouble and each show is a little different depending on the audience.”Osch, who played the caveman when the show was in Boston in December, said he is looking forward to returning to Boston.”We had a great run there,” he said. “The audience in Boston is great. People arrived ready to have a good time and we had a lot of fun doing the show there.”Osch said in prehistoric times men were hunters and women were gatherers, which is when he said the trouble started.”Hunters tracking prey had to be quiet, so men didn’t bond through conversation,” he said. “Women were gathers and bonded through conversation.”Comedian Rob Becker wrote “Defending the Caveman” over a three-year period during which he made an informal study of anthropology, prehistory, psychology, sociology and mythology.With hilarious insights on contemporary feminism, masculine sensitivity and the erogenous zone, “Defending the Caveman” addresses the common themes in relationships that go straight to the funny bone.Osch said the show has taken on a life of its own.”It’s a world wide phenomena,” he said. “It’s such a great night out even if you’re not a theater person. I’ve seen couples leave the show laughing and holding hands. This show really touches people and it’s hilarious.”Osch, who lives in New York City, has performed “Defending the Caveman” throughout the United States and Canada. He said some of his other favorite roles include Lt. Caffey in Aaron Sorkin’s “A Few Good Men”, Louie in Neil Simon’s “Lost in Yonkers” and Reverend Groves in Lanford Wilson’s “Book of Days.” Osch has also been seen on ABC’s “One Life to Live”, in various television commercials as well as many independent and short films roles.Performances of Defending the Caveman are at the Stanford Calderwood Pavilion, which is located at 527 Tremont St. in Boston’s South End.Tickets for all performances are $54 and are on sale online at www.bostontheatrescene.com and by calling 617-933-8600.
