While Cody Simpson and Ryan Beatty were in Los Angeles on their North American paradise tour, they stopped by On Air with Ryan Seacrest to perform one of John Mayer's hits, "Stop This Train"!
We're absolutely loving this cover! Their voices are so, well, beautiful -- have you ever heard anyone harmonize better than these two guys? We're completely amazed... and kind of in love.
What do you think of Cody and Ryan's cover? Let us know in the comments!
