I NEVER heard (until the last few years)the F word ANYWHERE, except in the Factories.
I never heard my grandfather,father,or son or grandson use the word...to MY generation it has ALWAYS been abhorrent and will remain so until the day I die.
I always turn off immediately any programme when the word is used.
It is the ultimately foulest word I have ever heard..this is how I was taught....BUT..
It is the word itself which makes me so angry.....IF we all were to use the another word, like 'fornication', I guess I could accept that................ 
Well, I guess WTF would still apply

, although it doesn't quite roll off the tongue as well.
Diki and Bachus are on the mark with their comments. It's funny how language conventions change. The first time, at age 13, I encountered the F-word, officially, that is, and to much giggling in the classroom, was during an English class reading Chaucer's Canterbury Tales where it's used a few times.
Regarding the F-version of the song, it was a British comedian, Roy 'Chubby' Brown who came out with it and, I did find it amusing on a trip to the UK to hear a bar band play the song with full, good-natured, audience participation at the appropriate points.

Influence-wise, it may be that today's young crowd probably initially picked it up from Rap artists with their urban street tales told in the language of the streets.
Change is constant, things will change again.
