Whitney Houston Death: Chris Cornell Delivers Moving Version of 'I Will Always Love You' (Video)
Among the many tributes to Whitney Houston comes this surprising performance by rocker Chris Cornell.
The Soundgarden and Audioslave frontman was performing at a fundraiser for President Obama on Thursday night in San Francisco when he delivered a solo acoustic cover of Houston's "I Will Always Love You."
A roaring crowd at the 3,100-seat capacity Masonic Auditorium can be heard cheering enthusiastically for the soulful rendition, which marries Cornell's grunge-grown vocals with melodies from Houston's version, which was itself an R&B interpretation of a country song originally by Dolly Parton.
Cornell is no stranger to awesome covers. His moody take on Michael Jackson's "Billie Jean" is a longtime favorite of fans and even made an appearance on American Idol, when season 7 winner David Cook used it as inspiration for his performance during the Top 10 week of the competition.
