...It's not just tacked on like a musical appendage. The band cuts out to a reprise of the solo guitar line that opened the tune. Is this the end? Is it over? No! The guitar repeats the figure a half-step up, and the band comes back in with the signature horn line in a whole new key!
The song is reborn! It's the same, but different! All the people get to keep dancing!.

Follow up Soul Man with Brickhouse and you might as well call the paramedics, but then, cover band setlist architecture is the subject of another post.
