The keyboardist pictured in this yearbook photo is the co-founder of one of the most beloved bands of the '60s and '70s. He's also a film director. A finely-trained eye can see the resemblance to how he looks nowadays due to his face shape. But today, there are a few added lines and wrinkles, which is to be expected when you have rocked as long as her has.

He was born on Feb. 12, 1939 and studied cinematography in the early '60s, which is where he met the now-late frontman of the band that would help define the rock 'n' roll landscape during their heyday.

The keyboardist also once collaborated with master parody maker Al Yankovic, and has continued to work with the guitarist of his aforementioned band in another project.
