Less “Don't Stop Believin'” and more “Don't Stop Bleedin',” the Greatest Concert Ever is that one shining opportunity for comedians to become the rock stars they always wanted to be. It's not a delusion of mass hysteria, of course — all these comics know that rock stars secretly want to be comedians — and host Matt Besser gives them the holiday gift of release in this, a hidden L.A. tradition since … 2006?! Mick Jagger, Billy Joel, Tom Waits — “they're” all here, backed by a crack commando unit of local musicians ready to overlook all the broken and flat notes vomiting past that noise you make in the back of your throat when you hear a joke. Past contenders include Horatio Sanz, Drunk History alum Michael Cassady, Key and Peele writer Colton Dunn, Eric Andre Show scribe Josh Fadem, Garfunkel & Oates and the proverbial “many others.” UCB Theater, 5919 Franklin Ave., Hlywd.; Sun., Dec. 22, 9:30 p.m.; $5.
