Paul McCartney was in New York on September 11, 2001, when the infamous terrorist attacks took place. He headlined the Concert For New York City just a few days later. In between, a film crew recorded the former Beatle's whirlwind media tour, that included interviews with Howard Stern, Dan Rather, and others, leading up to the concert.
Those interviews were culled together 10 years later for a Showtime special, The Love We Make, now available on DVD. There's also footage from the concert itself, with performances by David Bowie, Billy Joel, Elton John, Mick Jagger & Keith Richards of the Rolling Stones, The Who, and James Taylor, plus brief shots of Billy Crystal & Jim Carrey.
Following is a promo video from Showtime.
It all speeds by in a shade more than 90 minutes---it was made for cable, after all---, and the concert itself may still be available on DVD by itself, though I'd fast forward past Stern's on stage antics.
