Just felt the need to post this somewhere (2 days late unfortunately)...I grew up on 'Schoolhouse Rock' and we have lost a giant. Since these Saturday morning staples were a part of all of our lives in the height of pinball - go youtube 'Conjunction Junction' or 'I'm Just a Bill' and take a minute to remember.
Bob was the songwriter of MANY of the 'Schoolhouse Rock' tunes.
