"Child in Time", Deep Purple.
From "In Rock." Cool!
Oddball story time:
My dad took me to see them when they were promoting that album. I was only fourteen and could not travel, alone, half way across the state, but my dad was the coolest dad, ever. He took me to many concerts. I was not at all ashamed of being there with my dad. I thought it was like "power to me" and stuff. I'm sure I was a handful for him, though.
