The new TBS show, headlined by Brian Austin Green, stretches the sitcom format to an hour but doesn't quite know how to fill it. Still, it has its moments.
In "Wedding Band," which premieres Saturday on TBS, Brian Austin Green, who was on "Beverly Hills 90210" for a decade, plays Tommy, the lead singer and rhythm guitarist of an aging quartet available for weddings and bar mitzvahs in the rocktropolis of Seattle. (Local references in the script include Kurt and Courtney for the masses, the Tractor Tavern for the cognoscenti.) Spun a certain way, the premise might have produced a kind of younger musical companion to sister network TNT's late "Men of a Certain Age." But this is not that.
