Paul McCartney's 'Freedom' (2001)
Former Beatle Paul McCartney was moved enough by the attacks to write a song about them. McCartney witnessed the fall of the Twin Towers himself while sitting on the tarmac at JFK airport, and penned the anthemic track 'Freedom' on September 12, 2001. In the song, McCartney sings about how freedom is a 'right given by God', and is worth 'fighting for', which to some seemed at odds with his former band's anti-war sentiments. McCartney stopped performing the song after the invasion of Iraq as he felt it had acquired a 'militaristic meaning'.
