Besides the songs mentioned in the comments after the On This Day In Music History: Bob Dylan post, I heard and received several other titles in answer to the question above.
They were: “Tangled Up In Blue,” “A Hard Rain’s A Gonna Fall,” “The Times They Are A-Changin’,” “Blowing In The Wind,” “I Dreamed I Saw St. Augustine,” “Sad Eyed Lady of the Lowlands” and … none.
It’s not too late to add your choice to the list!
