If you IGNORE the person singing, I can name several from unlikely sources:
I’ll just mention Beatles’ Taxman, ‘cause it’s so obvious.
Kinks
Muswell Hillbilly
21st Century Man
Elton John (none of the three may qualify as straight rock and roll)
My Father’s Gun
Dixie Lilly
Georgia
David Bowie
Cygnet Committee
Think
Once You Understand
(just kidding on that one, but I include it because it unintentionally lampoons the lefty position on almsot everything)
I realized after posting that you just want real conservative bands/artists. That can be tough.
Don’t forget The Temptations “Ball of Confusion” and the Eagles “Get Over It”
Even “Imagine” is somewhat of a lampoon of lefty ideas.
No possessions, John? Not even a little recording studio or some piles of vinyl discs? Did you “share” the single with the world, or did it cost a few bucks per person? I guess your own imagination is lacking.
I still see the Beatles’ TAXMAN p!ss off liberals.
