It’s interesting, the percentage of progressive/left-leaning songwriters, singers, and musicians vs. those of the conservative/right-leaning persuasion. Make a list of your faves, and see where their allegiances lie.
Jackson Browne, Bonnie Raitt, Graham Nash, Bruce Springsteen, Ry Cooder, John Mellencamp, John Fogerty, John Hiatt (a lotta John’s around here ;-) , Iris Dement, Emmylou Harris, Joan Osborne, etc. on the left.
On the right? Ted Nugent and Mike Love. I don’t know much about Nugent’s music, other than that The Amboy Dukes’ version of "Baby Please Don’t Go" is unintentionally hilarious. As for MIke Love, we have to be embarrassed for him, as he’s too dumb to do it for himself.
I like what Dylan years ago said: "It’s not left or right, it’s up or down."
