I just bought a soundrtrack CD "In The Heat Of The Night" & "They Call Me Mr. Tibbs". It contains 20 tracks from ITHOTN including "FOUL OWL" & "BOWLEGGED POLLY". It also contains 15 tracks from TCMMT.

I got it through AMAZON. I got a used (Very Good) copy for about 10 bucks inc. S&H. They also show new copies starting at $ 39.99 at the moment.
