James Cagney stars in this unabashedly patriotic salute to the unabashedly patriotic entertainer George M. Cohan, whose songs are sung and danced by Cagney with great vigor. And what songs: Not only “The Yankee Doodle Boy” (better known as “Yankee Doodle Dandy,” but “Give My Regards to Broadway,” “Over There,” “Harrigan,” and “You’re a Grand Old Flag.” For the 4^th of July, it’s a perfect movie musical for the 4^th of July – as is the aforementioned 1776.
