Guess Who This Kid In His Rain Jacket Turned Into!

Before this blonde boy playing with his wheelbarrow turned into a singer and songwriter, he was just teaching himself how to play guitar -- by watching YouTube tutorials -- and hanging with his older bro Greg in their hometown of Mullingar, Ireland.
