Long train running is a title composed by Tom Johnstonthe guitarist singer of Doobie Brothers. Originally, it was an instrumental played exclusively on stage to warm up the audience and the fingers of the musicians! Besides, the piece has no fixed title or lyrics. At each interpretation, Tom Johnston improvises a different text according to his mood, with a result that is not always conclusive! The title has been performed on stage for three years now, when the group’s producer, smelling the hit, insists that this untitled song be included on their next album.
