DIAMOND HORSESHOE, 1945, starring Betty Grable

The real Diamond Horseshoe was a Las Vegas nightclub created by impresario Billy Rose, which spotlighted old-time stars from the early 20th century recreating the songs and skits that had made them great. Rose allowed 20th Century-Fox to use the name "Diamond Horseshoe" for a Technicolor musical, but only on the proviso that Rose's name be included in the title. Billy Rose's Diamond Horseshoe does have the occasional old-timer specialty, but for the most part the plot concentrates on Betty Grable, a young entertainer who romances would-be songwriter Dick Haymes. The affair is frowned upon by Haymes' father (William Gaxton), the manager of the Diamond Horseshoe, who is determined that his son pursue a medical career. The predictability of the storyline is redeemed by Haymes' rendition of the song hit "The More I See You", and by the comedy turns of Phil Silvers. ~ Hal Erickson, All Movie Guide

Song: Welcome To The Diamond Horseshoe Lyrics
Chorus:

Welcome to the Diamond Horseshoe, let the fun begin;
Say, mister, if you're keepin' your eye on the cute, cutie pie on the right,
You can meet her at the Diamond Horseshoe each and ev'ry night,
Including Sunday,
Each and ev'ry night;
She's off on Monday,
Each and ev'ry night.
