Since the sudden and tragic death of Whitney Houston, her biggest hit, I Will Always Love You, has been covered by everyone from Jennifer Hudson on the Grammys to the Valentine's Day episode of Glee. A video of water fountains in Dubai scored to I Will Always Love You also went viral after Houston's death.

Chris Cornell has now joined that club.

The Soundgarden front man's cover of Houston's hit has now been viewed by more than 1.1 million people on YouTube.

Cornell, 47, was on hand to support President Barack Obama at a fundraiser in San Francisco on Friday.

I just learned this so when I mess it up, just forgive me, Cornell told the crowd inside the Masonic Auditorium, before launching into his guitar rendition of I Will Always Love You.

Cornell has since re-tweeted his wife's posts of a photo and video from the fundraiser.

The Soundgarden singer most recently released the solo acoustic live album, Songbook, in November 2011. The band is set to release its first album in 16 years this spring.

One week after being found dead inside her Beverly Hilton Hotel, Whitney Houston was laid to rest on Sunday at the Fairview Cemetery in Westfield, N.J. The day before, more than 1,500 guests attended Houston's funeral at the New Hope Baptist Church in Newark, where friends like Kevin Costner, Tyler Perry and cousin Dionne Warwick spoke.
