The 18 Nov 1965 DV announced the start of filming on 29 Nov 1965 at the Moulin Rouge nightclub in Hollywood, CA. An audience of approximately 1,200 was given free admission to the event, which featured twelve contemporary bands and solo artists. Release of the film, provisionally titled This Could Be the Night, was scheduled for Jan 1966. The 2 Dec 1965 Los Angeles Sentinel revealed that singer and bandleader Ray Charles was guaranteed “a five-figure sum” for his performance. Charles had recently been hospitalized, reportedly for exhaustion.
       An article in the 1 Dec 1965 LAT referred to the picture as The Big T.N.T. (Tune ’n’ Talent) Show. The audience, described as “screaming teenagers and some older, long-haired hippies,” began congregating outside the Moulin Rouge at 3:30 p.m. After sitting patiently through multiple takes of host David McCallum conducting an orchestra, the crowd became restless until it was announced at 6:00 p.m. that refreshments were being served. The performances were covered by four television cameras “wired for more live definition.” The signal was sent backstage to “two RCA Recorders,” which captured the images on 35mm film and videotape, allowing technicians to edit performances as they happened. Post-production supervisor S. Richard Krown oversaw the backstage crew. The show, filmed over a two-day period, featured performances in the “rock ’n’ roll, folk-rock, traditional blues and country-western” genres. The article noted the flamboyant fashions worn by audience members, and a surprising venture into folk-rock music by “folk purist” Joan Baez. The picture opened 19 Jan 1966 in Los Angeles, CA, according to the 16 Jan 1966 LAT.
       A viewing of the film’s trailer revealed the presence of actress Teri Garr among the chorus dancers, and musician Frank Zappa as a member of the audience. The Moulin Rouge, formerly the Earl Carroll Theatre, is currently a television studio known as Nickelodeon on Sunset.
