Me too. My kids are more conservative than I am, and that's saying a lot. My husband is an army brat, my mom is pretty liberal (she's a professional dancer) but my dad is somewhere to the right of Attila the Hun. I still know all the words to Alice's Restaurant. It's a family tradition to play the song every Thanksgiving. My KIDS know all the words, too.
But just because you know a song doesn't mean you agree with every sentiment expressed by the singer. I mean (I mean, I mean) I know all the words to "Der Holle Rache Kocht in meinem Herzen," from The Magic Flute, but I'm certainly not going to encourage my daughter to stab her dad or try to overthrow the church (or the Masons, or whoever Sarastro is representing) . . . and I don't advocate such behavior in ANYbody. ;-)
