A 19-year-old British cellist wowed the crowd gathered in St. George's Chapel Saturday to watch Prince Harry wed American actress Meghan Markle.

Kensington Palace officials announced last month that Sheku Kanneh-Mason would perform at the wedding after Prince Harry saw him play at an event in London last year.

He stunned the 600 guests at Windsor Castle on Saturday with a rendition of Franz Schubert’s “Ave Maria” and other pieces of music.
