I used to have a copy of a 70s tune which was about 10 minutes long. The whole first half was a spoken story about a guy who was rich but said "with all this money there's still something missing from my life" followed by "what it is, what it is, tell me what it is". The guy in question kindly informed him that he was missing "S.O.U.L." Any idea what the song is? It's been driving me mad for ages and the all-powerful internet has yielded no results thus far.
