The Bay Area in the ’80s was a hotbed for live stand-up, with a dozen all-comedy nightclubs, including five in San Francisco alone, the city helped launch the careers of legends like Robin Williams, Ellen DeGeneres, Whoopi Goldberg, Bobcat Goldthwait, and Dana Carvey.

Comedian Mark Pitta also got his start in San Francisco in the ’80s, and for the past decade he’s been carrying on the Bay Area comedy tradition as the host and producer of Mark Pitta & Friends Tuesday Night Comedy at Mill Valley’s Throckmorton Theatre. Pitta says the idea sprung out of necessity; he was fired from his gig as morning host for KTVU and needed something to do. He chose Tuesday nights because it’s a day when most comedians are in between gigs. Each week Pitta books a mix of young up-and-comers and established headliners, then serves as the “Dean Martin” of the show, warming up the audience and riffing in between acts on whatever’s on his mind.

Backstage, the comedians relish the opportunity to catch up with each other in a low-key setting far from the cutthroat vibe of Hollywood. Pitta says a lot of comics stop by the green room on Tuesdays even when they’re not performing, just to hang out — something that’s especially appreciated by the young comedians, who get the chance to talk shop with the stars. “When I was starting out,” says Pitta, “there were a lot of clubs in San Francisco that supported new comics.” Now, he observes, “it’s more of a business — get the butts in the seats, get somebody who’s on TV.” He’s happy that the Throckmorton has become a place that can nurture young talent.

Because Pitta has long-standing relationships with the same comedy legends he came up with in the ’80s and ’90s, many of them perform at the “Throck” whenever they can. Robin Williams and Dana Carvey, both Marin locals, often take the stage to try out new material before they appear on late-night talk shows or head out on tour. “The Feng Shui of this theater is very positive,” says Carvey. “The room is shallow, so nobody is too far away.” Carvey relies on the Throckmorton and its supportive crowds as part of his creative process, noting that he “can really write a lot of material quickly with this theater.” Just six days after we taped his performance at the Throckmorton, national audiences of The Tonight Show were treated to some of the material Dana previewed in his Mill Valley appearance.
