Bob Dorough (born December 12, 1923) is an American bebop and cool jazz pianist, composer and vocalese singer.
He worked with Miles Davis and Blossom Dearie, and his adventurous style was an influence on Mose Allison, among other singers. He is perhaps best known as a voice and primary composer of many of the songs used in Schoolhouse Rock!, a series of educational animated shorts appearing on Saturday morning television in the 1970s and 1980s on ABC affiliates in the United States. Dorough composed, conducted and played much of the "Schoolhouse Rock!" music. He has released vocal jazz albums periodically over the last 50 years; his latest, Small Day Tomorrow, came out in 2006. He worked with Nellie McKay on her 2007 album, Obligatory Villagers as well as her 2009 release, Normal as Blueberry Pie - A Tribute to Doris Day.
