Seems like Don was only one of the boys of summer. This baseball coach remembers going to high school with Stevie.
From the Mercury News article on Gary Cunningham, college baseball coach:
Cunningham played baseball at Menlo-Atherton, where he fondly remembers sitting behind a pretty girl named Stevie Nicks in his senior English class. Nicks later sang with the group Fleetwood Mac; Cunningham went on to letter at San Jose State in 1969 and 1970.
