Pearl Jam frontman Eddie Vedder has been known to dabble in film music before. Perhaps most notably, he provided the soundtrack to the 2007 film Into the Wild. Friday in Italy, Vedder and the rest of Pearl Jam delved into someone else's film music by launching into the Oscar-winning song "Let It Go" from Frozen in the middle of performing their hit "Daughter." It happened at the band's show at Stadio San Siro in Milan.
