Justin Bieber was recently visiting London, and decided to surprise pedestrians with some impromptu busking.

Sitting on a fountain outside of Buckingham Palace, Bieber busted out an acoustic guitar and played some songs for his fiancée, Haley Baldwin, and passersby. Among the clips of songs people filmed and uploaded online was Housefire’s “Good, Good Father.”

Watch the clip of Bieber doing his best impression of every single dude attending Christian college that owns an acoustic guitar.
