Hundreds of mourners gathered at a Detroit church on Friday for a music-infused funeral for Aretha Franklin, featuring tributes by former U.S. President Bill Clinton and singer Stevie Wonder to the Queen of Soul, who died this month at age 76. Reuters reports the funeral included performances by those influenced by Franklin?s singular, soaring voice, including singers Chaka Khan and Ariana Grande. Having sung at the inaugurations of three presidents - Jimmy Carter, Bill Clinton and Barack Obama - Franklin was an American institution.
