I first noticed song titles that appeared nowhere in the lyrics among Bob Dylan songs, starting at about the same time as the electric-guitar controversy, e.g., "Love - Zero / No Limit," "Positively Fourth Street," "It Takes a Lot to Laugh, It Takes a Train to Cry," etc.

In some cases (like the above-cited three), I could see how the titles were appropriate; in other cases, I didn't understand the titles and felt vaguely offended.

As in so many other situations with Mr. Bobby, it looks like he took a long-standing feature of traditional folk music and reinterpreted it on his own terms.
