Lyric discussion by Gradle 

Cover art for Jenny lyrics by Harry Chapin

These lyrics are referring to New York City and Los Angeles:

I have seen a great city in darkness (NYC had a major blackout in 1977, the year before this song was written)

Green lady dressed in cold concrete (Statue of Liberty)

I've seen the City of Angels (nickname for LA. It's Angels not angles)

With the names of its dead in the street (Hollywood Walk of Fame)

Miss ya, Harry! <3
