I seem to remember the words to the Theme from Midnight Cowboy making reference to someone croaking on a Greyhound bus, but my memory has been known to fail me before. May-be the Brazilian version of Midnight Cow-boy removed it for aestetic reasons. Or the Brazilian band Modern Sound Six thought it didn't work well with their Kool and the Gang cover and a nearly unintelligible version of Born to Be Wild.
