Showtime is 8 p.m., with $8 admission and discounts on organic wine and craft beer during the show (as Dean would surely appreciate).

The Psychotronic Film Society’s long-running weekly series of unpredictable and underappreciated motion pictures continues with a slight anomaly. The PFS pays tribute to the life and legacy of the late, beloved singing actor and comic Dean Martin on the 100th anniversary of his birth — however, they are not doing so by showing one of Martin’s many feature films. Instead, they will screen a specially made 75-minute compilation of rarely seen highlights from Dean’s infamous NBC-TV variety show, which ran from 1965-74 (for an amazing 264 episodes), but has never been shown publicly since.

Packed with a veritable who’s who of guest stars (including top comedians, actors, musicians and vocalists), that series found Martin holding court and interacting with a wide swath of household names in all sorts of ways — from campy sketch comedy to schmaltzy song-and-dance numbers — with an ever-present highball glass and cigarette in tow.

This selection of standout routines and musical performances from Martin’s variety show was curated just for this one-night-only screening, and functions as a time capsule of Hollywood and network TV from that period.
