Susan Boyle moved mourners at a friend's funeral to tears when she performed AMAZING GRACE at the ceremony.
The Britain's Got Talent star's pal Molly Burnett passed away in Scotland last month (Mar10), and her friends and family rallied around to give her a fitting farewell.
And Boyle offered to sing at the church funeral earlier this week (begs29Mar10).
Burnett's sister says, "We were so grateful she took the time."
