When opening the Grateful Dead's album "Aoxamoxa" there is a picture of the band sitting in front of a tree with a group of children. One of these children will grow up to be a famous rocker. Who?

Courtney Love, her Dad, Hank Harrison drove the Grateful Dead bus when the picture was taken.

According to this site, the little girl is Stacy Kreutzmann.

For years, there has been a rumor that the five-year-old Courtney Love was on the back cover of Aoxomoxoa - the girl in the front, sitting next to Pigpen. This story has been repeated so often, it's become an internet "fact," supposedly confirmed by David Gans and even mentioned in official Dead writings. Here's one site that tells the tale:
