Humorous folk song written to protest a fare increase to ride the Boston Metropolitan Transit Authority subway, most memorably performed by the Kingston Trio. The protagonist pays his dime to get on the subway, but when he tries to get off he's told that the fare has gone up by a nickel; fishing in his pocket he finds that he can't afford to leave the train.

Chorus:

Well, did he ever return? No, he never returned, and his fate is still unlearned.
(What a pity! Poor ole Charlie. Shame and scandal. He may ride forever. Just like Paul Revere.)
He may ride forever 'neath the streets of Boston. He's the man who never returned.
