I love the song but he could've shorten it down to one side of the record, some records only had one vocal side being 15 minutes long, but there is also versions which had a continuation of the song being an additional 8 minutes long.

The first part has a long storyline then breaks into a few call & response chorus parts but when you hear the second part of the song you realize he didn't finish the storyline on the first part; but these were how most rap songs were in the early 80's, disco party style to be played in clubs to keep people engaged on the dancefloor.
