Happy Father’s Day! If you haven’t seen this father-son cover of the Beatles’ song “Don’t Let Me Down,” there’s no better time than today to tune in. This is what being a dad is all about – spending time with your tot and nurturing his talents. Going viral on YouTube is just icing on the cake! This video is so precious (that mini guitar!!) it brought tears to my eyes. Diogo Mello and his dad have had their Beatles tribute band going on pretty much since he was born (and he’s not even two yet). This toddler is giving John Lennon a serious run for his money. Someone needs to sign him stat. Let’s just hope there’ll be no Yokos in his future – I wouldn’t want anyone breaking up this adorable duo!
