Bing Faithful's Very Merry Nondenominational Holiday Special

Bing Faithful (improviser Bob Kulhan) takes to the stage as the only surviving member of the Bing Faithful 5, singing holiday hits (both his parts and the parts of his late band members) as requested by the audience. Later it is revealed that the band is alive, but bloody and intent on individually confronting Bing midshow as he's singing.
