"When You Got a Good Friend" is a blues song recorded on November 23, 1936, in San Antonio, Texas, by Robert Johnson. The song was unissued until 1961, when it was included on the LPKing of the Delta Blues Singers.
Johnson performed the song in the key of E, and recorded two takes, the second of which was used for the LP.[1] Both takes are included on the album The Complete Recordings.
The song uses the melody made popular by the hit recordM & O Blues by Walter Davis. Johnson composed two songs to this melody - "Ramblin' On My Mind" and "When You Got A Good Friend" - with different musical approaches and different guitar tunings, although both were in the key of E.[2]
