Do you ever sing to music you know, when you hear it playing? When there is a concert on PBS, that we like, we will. Wife loves singing to some Oldies she knows and definitely to Motown tunes. Sometimes she will even jump up out of her recliner and dance. I think it's cute as heck. Since I'm the "Rocker"/former drummer, of the family, when I hear Classic Rock playing, I will get my hands/arms going like I'm playing a full set of Ludwig drums again. Wife loves it. And, I also know some of the words as well.
