This raven-haired beauty, now 62, went on to achieve an impressive measure of fame fronting a band alongside her guitar-playing little sister. She looks so sweet and innocent, right? This photo, which dates back to 1968 when she was in high school in Washington State, shows a softer side of the now bold singer.

The frontwoman's band had a string of radio-driven hits in the '70s and '80s, and the band remains hard at work up until this day, with a new album due this fall as well as a memoir that she and her sister co-wrote.
