Lewis won a Facebook contest giving him the rare chance to conduct all 360 voices and 80-piece orchestra.
“It felt like a dream, it felt like I was Mickey Mouse in Fantasia,” he said.
Last June, the Mormon Tabernacle Choir invited fans across the United States to enter the online contest.
Lewis beat out the others and left his home in the state of Virginia to come to Temple Square, a place where he married his wife five years ago.
Now he's making another memory.
“The choir has gotten me through a lot in my life so just the opportunity to just stand there, the best location of all, it's the ultimate surround sound and a wild experience and I will remember it forever,” Lewis said.
Lewis conducted Beethoven’s “Hallelujah Chorus”.
