What is bring it on home john b?

"Bring it on Home" is a blues song written by American musician Willie Dixon. The song is best known for its rendition by the English rock band Led Zeppelin, which was included in their 1969 album "Led Zeppelin II". However, "Bring it on Home" John B is likely a reference to John B. Sebastian, a songwriter and musician who was a member of the Lovin' Spoonful, a 1960s rock band. He is known for the song "Welcome Back" which was used as the theme for the TV show "Welcome Back, Kotter". It is unclear how "Bring it on Home" relates to John B. Sebastian, as he did not write or perform on the Led Zeppelin version of the song.
