"Richard Cory": Compare and contrast the poem and the song.Like the context or the structure' or anything else. Thank you!

Both the poem and the song are among my favorites, and
fully worth re-reading or listening to again.  I encourage you to come up with a more
detailed analysis, but I will help you get started with context
comparison.

First of all, the subect
of both the poem and the song lyrics is the same person, Richard Cory.  He is well known
around town, wealthy, respected, and envied.  The speaker is the
same as well, as both are told from a first-person point-of-view.  Both end in the same
dramatic irony with the man who seemed to have everything
committing suicide.

The biggest differences between the
poem and the song lyrics is the song lyrics are more detailed.  It is almost as if the
song gives the story behind the poem.  Notice the refrain of the song, "I work in his
factory."  The speaker here is not just one of the many people in the town who has hears
of or sees Richard Cory on a regular basis.  It is a man who works for Richard Cory. 
The song lyrics do not suggest a personal relationship (factory work is hardly
personal), however, the speaker has a bit more credibility in the song.  The song also
goes into more detail about Richard Cory.  Everything is contextually relevant, and
sounds like it could be true based on the few clues from the
poem.
