1943. Kinda sounds like the Boogie Woogie Bugler Boy of Company B at the start. As a string, keyboard and percussion musician (occasional vocals), I am always amazed with brass musicians who can play in tune.
The lead vocalist in this blows away all the hyped celebrity crap, politically correct non-White or self hating White vocalists with their goofy costumes and silly drama making millions off stupid, ignorant fans of garbage.
