We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
It's not just the Japanese that have appropriated C&W music. New Englanders have done it, too. Yankee Twang: Country and Western Music in New England. [Given the specific definition in New England of Yankees- those descended from English who arrived in New England before the Revolutionary War- I didn't write my second sentence as "Yankees have done it, too."]
A classmate of my sister in our NE hometown has converted her parents' acreage into various moneymaking activities, including a barn that features C&W dancing in warm weather.
IMAO, American C&W was a main export after WWII and Korea. Many GIs were from what we now call Flyover States, and their subculture went with them to Japan, Germany, Korea, the Philippines, Okinawa, etc. Armed Forces Radio also leaned toward providing music and programming that their GI audiences preferred, so C&W was much of the programming. Even into the Vietnam era, C&W was initially a fixture in AFVN programming.
So it followed, if you wanted to make money in a bar playing for GIs, you played C&W. And C&W music became grafted on to other cultures.
This, of course, has changed over the years and other pop, rock, r&b, rap, modern Nashville and Austin music have risen in popularity.
Nonetheless, old-style C&W is still found in many of the areas that GIs once occupied.
