There was some great music in 1973 from Gladys Knight (Neither One of Us), Isley Brothers (That Lady), The Temptations (Masterpiece) and Harold Melvin and the Blue Notes (Love I Lost).
But, I decided to go with Billy Preston. I sported a large afro for most of my high school years ... and that was the deciding factor in choosing the 1973 hit song, Will It Go Round in Circles.
Did you ever see 11-year old Billy Preston when he made his national television debut in 1957 on The Nat King Cole Show.
