Frishberg was a prolific jazz composer, lyricist, and vocalist, best known for his songs on the series 'Schoolhouse Rock!,' such as "I'm Just a Bill." He died Nov. 17 at age 88. Many of his songs were witty, including "I'm Hip" and "My Attorney Bernie." But he also wrote beautiful ballads, like "Heart's Desire" and "You are There." Frishberg came to the 'Fresh Air' studio in 1998 to play some of his songs and talk about them.
