Stevie Wonder and the Rev. Al Sharpton were among the celebrities that came out for Etta James' funeral on Saturday. By the end of the ceremony, filled with a slew of tribute performances, everyone seemed to be talking about Christina Aguilera's soulful rendition of 'At Last.'

"It isn't every day that an artist can meet the person who inspired them and their career," 'The Voice' judge told PEOPLE magazine. "Not only did I have the incredible opportunity of meeting my idol, the legendary Ms. Etta James, but to be asked by her family to perform at her memorial was so very touching and yet bitter sweet."

James, the legendary blues singer, passed away from complications with her leukemia while surrounded by her family.
