Robert Lrod Dorough (December 12, 1923 – April 23, 2018) was an American bebop and cool jazz vocalist, pianist, composer, songwriter, arranger, and producer. Dorough became famous as the composer and performer of songs in the TV series Schoolhouse Rock!, as well as for his work with Miles Davis, Blossom Dearie, and others. Early life Robert Lrod Dorough was born in Cherry Hill, Polk County, Arkansas and grew up in Plainview, Texas. During World War II, he participated in Army bands as pianist, clarinetist, saxophonist, and arranger. After that, he attended North Texas State University, where he studied composition and piano. Career From 1949 to 1952 Dorough was a graduate student at Columbia University in New York City, and on the side played piano at local jazz clubs. He was hired for a tour by boxer Sugar Ray Robinson, who had interrupted his boxing career to pursue music. In Paris from 1954 to 1955 he worked as a musician and musical director, recording with jazz vocalist Blossom Dearie. When Dorough returned to the United States, he moved to Los Angeles, where he performed in various clubs, including a job between sets by comedian Lenny Bruce. His first album, Devil May Care, came out in 1956 and contained a version of Charlie Parker's "Yardbird Suite" with lyrics added by Dorough. Jazz trumpeter Miles Davis liked the album, and in 1962 when Columbia Records asked Davis to make a Christmas record, he sought out Dorough to provide lyrics and vocals. "Blue Xmas" appeared on the compilation album Jingle Bell Jazz. During that session Dorough recorded another song for Davis, "Nothing Like You," which appeared a few years later at the end of the Sorcerer album, making Dorough one of the few musicians with a vocal performance on a Miles Davis record. In 1969, Dorough participated as arranger, choir vocalist, and pianist for beat poet Allen Ginsberg's 1970 LP Songs of Innocence and Experience, a musical adaptation of William Blake's poetry collection of the same name. From 1972 to 1996, and for direct-to-video releases in 2002 and 2009, Dorough wrote and directed episodes of Schoolhouse Rock!, an educational animated series that appeared on TV. He got the job when advertiser David McCall asked him in 1969 to put the multiplication tables to music, with "Three Is a Magic Number" earning him the job as the series' musical director. Dorough wrote all the songs
