Remembering schoolhouse rock composer Bob Dorough

Fresh Air:

We remember jazz composer and singer Bob Dorough, who died this week at 94. He was best known for songs he wrote for ‘Schoolhouse Rock!’ like “My Hero, Zero” and “Three is a Magic Number.” He spoke with Terry Gross in 1982 and 1996. Also, jazz critic Kevin Whitehead reviews a four-disc reissue of Louis Armstrong.
