sutlin was n't a stupid man and part of him knew this was self-serving bullshit , but part of him was also exalted by the idea of it , and as he got back into his car and drove off , leaving prince standing at the side of the road and looking after him , he was whistling the theme from born free , occasionally bursting into a snatch of the lyrics : `` booorn freeee ... to follow your heaaaart ! ''
