Anybody know anything about a picture titled Las Vegas By Night?

According to IA the picture billed on that 1963 A&W promo as “Las Vegas By Night” was ultimately released in 1967 as Spree (also advertised as Las Vegas by Night and Here’s Las Vegas). It’s a nightclub/Las Vegas documentary featuring Vic Damone, Juliet Prowse, Jayne Mansfield, the Clara Ward Singers and others, shot largely at the Tropicana and Dunes in 1962–63.

tguernsey: "Las Vegas by Night" must be the working title for the film listed in IMDb as Spree (1967) at https://www.imdb.com/title/tt0062299/ for the following reasons: 1. "Spree" features Vic Damone as himself. 2. The plot description indicates that "Spree" is about nightlife in Las Vegas. 3. Hal Roach Jr. and Carroll Case are listed as producers of "Spree". 4. Mitchell Leisen is listed as one of the directors of "Spree", and it is the only film he is listed as directing after 1960. In addition, the AFI Catalog (https://catalog.afi.com/Film/18547-SPREE) indicates that "Spree" was filmed in 1962 and 1963 under the title "Las Vegas by Night".

“Interesting! I can’t find any record of a film called Las Vegas By Night. It may have been a TV special, promo short, or a working title that was never released. Checking old trade mags (Variety/HR), AFI, or film archives under Mitchell Leisen or Hal Roach Jr. might give more clues.”
