Lyric discussion by dolfan 

Cover art for Taxi lyrics by Harry Chapin

I heard an interview with Harry Chapin back before he died when I was working at WGBS in Miami. He said he was actually a cab driver and had heard his old girlfriend was in town and he started to think what would she say if he picked her up as a fare. He was terrified of how she would react if this happened and she saw that all he had done with his life (his singing career had not yet taken off, of course). He had this vision of her getting in his cab and saying, and here I can quote the comment he made verbatim, "Harry, what happened to YOU?"
