3. Concert for New York City, 2001

On October 20, 2001, a little over a month after the 9/11 attacks at the World Trade Center, Paul McCartney organizes the Concert for New York at Madison Square Garden to honor the first responders, victims of the attacks, and those continuing to work on the site. Bowie opened with Paul Simon’s “America,” followed by his own song “Heroes,” which he dedicated to his local New York Fire Department company.  The star-studded affair included performances by Mick Jagger, Keith Richards, Jay Z, The Who, Bon Jovi, James Taylor and many more, with celebrity introductions by the likes of Bill Clinton, Natalie Portman, Robert De Niro and more.
