Out of This World (2004)

Five young musicians, each harboring painful memories, are assembled to entertain American soldiers at an Enlisted Men's Club. Tensions emerge between the tenor saxophonist, a disillusioned ex-soldier, and a bitter GI whose brother was killed in the war. And when the band plays the prohibited "Danny Boy" during a birthday bash for a sergeant whose son Danny had died a year ago, everyone must confront a past they'd rather forget.

Unfortunately the movie Out of This World is not yet available on HBO Max.
