A year after being exonerated for a crime he didn't commit and released from Angola prison, Baton Rouge resident Archie Williams is on 'America's Got Talent,' where for his audition he sang  Elton John's 'Don't Let the Sun Go Down on Me.'

Archie Williams, the Louisiana man whose heartbreaking personal story of wrongful imprisonment and soulful singing touched the hearts of judges and viewers of the TV show "America's Got Talent," will appear again on the show Tuesday, Aug. 11.

Archie Williams wrongfully spent decades at Angola. Now he's a budding 'America's Got Talent' star.

Williams, 59, spent almost four decades in prison but was freed after DNA evidence proved his innocence. While incarcerated, he would watch "America's Got Talent" and visualize himself performing.

He fulfilled that dream and appeared on the show in May. Even before the show aired, a video of him discussing his prison ordeal went viral, racking up millions of views on YouTube.

Williams is among the singers competing for a $1 million prize.
