“We made the recording, had full costumes and choreography,” Clayton says. “That’s Blake’s favorite number and he’s always wanted to do it, but he’s too scared to dance in front of people.”

“So they danced for me,” Knight says. “It was pretty fantastic.”

Clayton calls his favorite part of the day the merging of his and Knight’s families. “The blending of our worlds fully and wholly really felt like my favorite part,” he says. “Everyone got along, everyone had an amazing energy and made the day. It was full of joy.”
