Comedy is hard. Last season brought a revival and revolution of sorts to the sitcom, ushering in “New Girl” and “2 Broke Girls,” and the presumed dawn of female-centric sitcoms. This season has arrived with a spate of new comedies. With the exception of “The Mindy Project,” few of them are memorable.

In the face of this trend, TBS launches something entirely different. “Wedding Band” (9 p.m. Saturday) is an hourlong, guy-centric “bromance” comedy. And it’s on Saturday night.

A wedding band is a natural setting for a comedy, combining the slacker wish fulfillment of “School of Rock” with the raunchy hedonism of “Wedding Crashers,” ”Bridesmaids” and “The Hangover.” “Band” follows the four members of Mother of the Bride, an “indie” wedding band consigned to playing low- to midlevel banquet halls.

”Band” has some clever concepts. The band chafes at their low place on the wedding circuit food chain. They need a big break with a slick event management company run by Roxie Rutherford, played by Melora Hardin, who was spot-on as Jan on “The Office.”

Despite its promise, “Band” falls apart when it becomes obvious that it’s an hourlong effort with the heart and brains of a half-hour sitcom. Like a manufactured boy band, the guys seem more like a collection of types than genuine characters.

The real mystery is why TBS chose to broadcast this experiment on Saturday nights, when a large portion of its potential male audience is probably watching college football.
