Stevie Wonder also performed at her funeral.

Rev Al Sharpton, who spoke at her funeral dwelt on the legendary singer's inspiring career - how she came from a poor family, fought drug addiction and made a successful musical career. The Reverend read a statement from President Barack Obama, who paid tributes to the R&B singer by describing her as "Etta will be remembered for her legendary voice and her contributions to our nation's musical heritage".

The "At Last" song was performed at Obama's inaugural ball in 2008 by Beyonce.
