It was a documentary-style parody or mockumentary of the HBO (and later Bravo) network's reality television series Project Greenlight.
The new show ostensibly stars New York City theatre and television actor Peter Gallagher (again playing a fictionalized version of himself), but when Gallagher is hit by a motorist during the filming of a network promotion, the lead role is shifted to comedian Patrice O'Neal.
During rehearsals for the premiere episode, the actors, crew and producers all start fighting each other (and themselves), and "Jesus and the Gang" is permanently shelved.
Contest Searchlight was shown in a pseudo-documentary style, and there was no laugh track or other obvious sign that this was a fictional series.
A fully produced version of the "Jesus and the Gang" theme song appears as the eighth track on Leary's 2004 album, Merry F#%$in' Christmas.
