One Day in Hawaii a guy is playing a song in a coffee house when a total stranger decides to start singing along with him. The stranger is a pretty good singer and he knows the words to the song perfectly so for the street musician this ends up being OK. Turns out the reason the stranger can sing the song “One Day” so well is because his name is Matthew Paul Miller. He’s better known by his stage name of Matisyahu and he wrote the song that became a hit back in 2009. What an awesome experience for this coffee shop musician.
