A song that makes me happy. So I guess that means nothing by James Taylor... :)
"Age of Aquarius/Let the Sun Shine In" by the 5th Dimension. I am too young to "get" this song from when it came out--or maybe there's nothing to get--but I love when it comes on in the car and I can crank it up and sing along. I picked it up on vinyl about 14 years ago and listened to it nonstop while I cleaned our first little apartment on South Grand. Tiny place but what a dump. I'd play this song loud and try to shovel the place out.
I noticed when we were getting rid of Mike's old turntable stereo from high school, that this record had been left on it for who knows how many years. Somehow (I blame cats), a notch had been cracked into the side. Unplayable, I didn't throw it away. I put it back in its jacket. Maybe I'll melt it over a can of tomatoes someday and make a bowl.
Lots of songs make me happy, but this one does relentlessly.
