Patrons at a downtown Toronto pub may have done a double take on Friday night when pop star Justin Bieber sat down at the piano and played a few songs.

Fifth Pubhouse, located at Richmond Street West east of John Street, issued a news release Sunday saying Bieber wandered in alone, ordered a drink and watched the Toronto Raptors' game.

The pub says he spied a piano and asked staff if he could play it.

A few posted YouTube videos captured the impromptu performance.

According to the pub's news release, Bieber played a number of songs including the Beatles Let it Be and his own song Sorry. He also play a few bars of Beethoven's Fur Elise.

Pub owner Oliver Geddes says the Canadian pop star was gracious to both staff and customers at the entertainment district bar.
