There’s nothing like a father and son duet to really warm your heart! Acoustic musician Brent Stimmel grabs his guitar, and then his little boy joins in for the cutest version of the Beatles’ “Love Me Do.”

He takes the harmonica and sings along with his dad to create the best rendition I’ve ever heard! It’s a good thing Mom had the camera ready to record this heartwarming video. Right in the middle of their song, the little guy decides to put on a robot costume for their performance! Forget music lessons because this three-year-old is already a harmonica pro!

Watch this adorable duo and make sure you SHARE with your friends on Facebook!
