This weekend Laugh USA on Sirius XM becomes Second City Comedy Radio, a two-day channel celebrating the 50th anniversary of the iconic improvisational comedy theatre.

The two day limited-run channel will run all day Saturday and Sunday (December 12th and 13th) featuring comedic sketches and interviews with past members of the troupe.

The Second City Theatre opened on December 16, 1959 in Chicago and has since expanded its presence to several other cities, including Toronto and Los Angeles. The style of comedy has changed with time, but the format has remained constant. Second City revues feature a mix of semi-improvised and scripted scenes with new material developed during unscripted improv sessions after the second act where scenes are created based on audience suggestions.

Past alumni are a veritable "who’s who" of comedy and include: Stephen Colbert, Martin Short, Andrea Martin, Eugene Levy, Joe Flaherty, Dave Thomas, Jim Belushi, Steve Carell, Dan Castellaneta, Jeff Garlin, Isabella Hoffman, Richard Kind, Robert Klein, Jack McBrayer, Harold Ramis, Horatio Sanz, George Wendt and Fred Willard.

The channel will also feature various sketches from stage shows from the past fifty years, including "Picasso's Moustache" from 1971, "Peace and Serenity" from 1969, "To the Water Tower" from 1963, "My Friend Art is Dead" from 1962 and "Survival Kit" from 1982.

Second City Comedy Radio airs on Sirius channel 105 and XM channel 151.
