Bruce Springsteen (2009)
Like the preamble to Bill Clinton's first swearing-in, Washington, D.C. hosted an all-star concert ahead of Barack Obama's inauguration, dubbed, "We Are One: The Obama Inaugural Celebration at the Lincoln Memorial." Performers included John Mellencamp, Garth Brooks and show-stopper Beyoncé, but one of the most affecting moments was Bruce Springsteen's rousing, gospel-singer-backed rendition of "The Rising," a song about firefighters who died on 9/11. He played acoustic guitar and sang along with dozens of culturally diverse choristers, dressed in red and white. Video of the performance shows Obama, chin high, taking it all in.
