"Good Morning, School Girl" is a blues standard which has been called "an important influence in Chicago blues". The song was first recorded by pre-war Chicago blues vocalist and harmonica pioneer John Lee "Sonny Boy" Williamson in 1937. A variety of artists have recorded versions of the song, usually calling it "Good Morning Little Schoolgirl".
Sonny Boy Williamson I recorded "Good Morning, School Girl" in 1937 during his first recording session for Bluebird Records. The song is an uptempo blues with an irregular number of bars. Although identified with Chicago blues, "it was a product of Sonny Boy’s west Tennessee roots and his pre-Chicago ensemble work". The melody has been traced to “Back and Side Blues”, a 1934 blues song recorded by Son Bonds. "Good Morning, School Girl" features Williamson's vocal and harmonica with accompaniment by Big Joe Williams and Robert Lee McCoy (also known as Robert Nighthawk) on guitars.
In 1961, Don Level and Bob Love, as the R&B duo "Don and Bob", recorded a different version of "Good Morning Little Schoolgirl" for Argo Records, a Chess subsidiary. Although it uses the phrase "good morning little schoolgirl", the song has different chord changes and lyrics, including references to popular dance styles of the time.The Yardbirds with Eric Clapton later covered this version of "Good Morning, Little Schoolgirl" for their second UK single in 1964. The song reached number 49 in the UK and although the single was not released in the US, it was included on the Yardbirds' first American album, For Your Love. A live version of the song was included on Five Live Yardbirds, which featured Clapton and bassist Paul Samwell-Smith providing the vocals instead of lead singer Keith Relf. The Yardbirds versions were credited to "H.G. Demarais" (aka Dee Marais, a Shreveport, Louisisana, record label owner/distributor and business associate of Leonard Chess), although some later reissues are credited to Sonny Boy Williamson; the original Don and Bob single list the writers as "Level-Love".
