Dylan may have borrowed the title and chorus line from a gospel song titled "Wake Me, Shake Me
." That line goes:Try to make it in due time
Before the heaven doors close
In 1966, The Blues Project covered "Wake Me, Shake Me." One of the members of that band was Al Kooper, who was a friend and frequent collaborator with Dylan. Dylan may be familiar with the song through that channel, though he also might have heard it in the original, of course. Either way, the lines are awfully similar.
