I recommend this film despite the low rating. Though it is saddled with a simple story and it has a disjointed narrative, it features a plethora of stars and some memorable moments.
The story revolves around a base where military personnel wait for deployment in the Korean conflict. Some Warner Brothers stars (e.g. Doris Day, Ruth Roman, and Gordon MacRae) who play versions of themselves entertain the troops there. The story eventually settles into a plot about an Air Force crewman who is a hometown acquaintance of star Nell Wayne (Janice Rule). But just as that story becomes interesting, it shifts to another, unrelated musical performance.
But some of those vocal performances are very enjoyable, especially those by Day and MacRae. Jane Wyman also sings. Look for the dancing of Janice Rule. And Virginia Gibson, who performs as a saloon girl in a musical number featuring Gary Cooper and Phil Harris that is very entertaining.
Addendum 10/20/23: Among the many beauties in the film, watch for Patrice Wymore., a knockout who taps and sings with an all-girl band. Patrice was married to Errol Flynn until his death.
