Justin Bieber delighted patrons of a pub in Toronto, Canada on Friday (04Nov16) with an impromptu piano concert.

The Canadian singer visited the city's Fifth Pubhouse to grab a few drinks, and decided he would perform there.

The 22-year-old musician, who won three MTV Europe Music Awards (EMAs) on Sunday (06Nov16), performed his hit Sorry, The Beatles' Let It Be, and a section from legendary German composer Ludwig van Beethoven's classical piece Fur Elise.

Video footage of Justin's virtuoso moment was posted on YouTube over the weekend. It showed the crowd in the bar erupting into applause when he finished playing.

Dale McDermott, who was working in the pub at the time, tweeted: "I was working in my bar, Justin Bieber came in on his own to get a few beers. We talked about Ireland and his visit."

Others who were in the pub insisted Justin was in good form, with one Twitter user writing: "I am not of the age to be a Justin bieber (sic) fan, but was in a bar on Richmond st. (Street) in Toronto with him and he is a great kid."

Staff at the pub - in Toronto's entertainment district - thanked the pop superstar on the venue's Facebook page, writing: "Thank you Justin Bieber for giving us this great Canadian moment at our Great Canadian Bar!"

Although Justin was the biggest winner at the MTV EMAs in Rotterdam, Netherlands on Sunday, he did not attend the ceremony.
