Grace Slick is celebrating her 73rd birthday today. Grace was the lead singer of Great Society, Jefferson Airplane, and Jefferson Starship. She also did a few solo albums.She has one daughter, China who's father is former Jefferson Airplane guitarist Paul Kantner with whom Slick had a relationship from 1969 through 1975. During her hospital stay after the baby's birth, Slick sarcastically told one of the attending nurses (whom Grace found annoyingly sanctimonious) that she intended to name the child "god", with a lowercase "g", as she "wished for the child to be humble". The nurse took Slick seriously, and was the birth of a rock-and-roll urban legend.
