The Armed Forces of the United States consist of the Army, the Navy, and the Marines. We have always been given to understand that the Marines had the inside track with the fair sex, but in the theme song of "Navy Blues" the much-ballyhooed Navy Blues Sextette maintains that that sailors have the edge. Sailors, it seems, are divided into officers, and gobs. The officers, who are, of course, gentlemen, appear in the foreground only as the source of unpleasant but necessary orders, and in the background only to the accompaniment of soft music and lovely ladies, observing tolerantly the antics of the gobs. In fact, that whole picture calls up nothing so vividly as the recruiting poster outside the local postoffice.

The series of alternating songfests and bursts of earthy, or rather marine humor are strung together by a plot involving the fleet gunnery prize, an expert gun-pointer whose hitch expires just before target practice begins, and the girl who persuades him to re enlist. Jack Oakie, who has staked his petty officer's savings and his ship's trophies on the outcome, exercises more ingenuity and resourcefulness than his script-writers. Martha Raye opens her mouth wide, and makes faces, Ann Sheridan is also in the cast

"Gay Falcon," which completes the bill, is a better - than-average murder mystery, complete with two corpses, jewel thieves, and dialogue clever enough to clear away those navy blues.
