"child in time" by Deep Purple. My whole life this song would randomly get stuck in my head. I remember trying to figure this out at the bar when I was 30 with a bunch of people there and we figured it might be Rainbow. So I went home and listened through every Rainbow song, including the crap after Dio left and nothing. It drove me crazy, I even thought I made it up in my head lol. I cant remember how, but I eventually figured it out a few weeks later.

My dad loved Deep Purple so thats probably where the seed planted. lol
