Thanks for the answers. :)
      
    When I first listened to it, I thought that it was only the chorus of the song or just piece of it... But now I'm wondering... Josh white had a radio show Called "My Guitar Is Old As Father Time", was the show named after the song(if this is the case, I think that this is just the chorus), or the song was written to open the show(if this is the case this could be the whole song) If anyone know the answer please tell me!

Ps.: Sorry for any mistakes, English is not my first language
