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

in 1963 A&W Restaurants put out a promotional record titled "Vic Damone Swings With A&W". On the record sleeve is mentioned a picture titled "Las Vegas By Night" as the picture where the songs were originally sung by Mr. Damone. It indicates the movies Executive producers were Hal Roach, Jr. & Carroll Case, Producer: John Maschio, director: Mitchell Leisen. It was a United Artist release. I can't seem to find out anything about this Picture.
