North East singer James Arthur left his fans shocked after he played an impromptu show inside a London train station.

The singer/songwriter, who hails from Middlesbrough, may have clinched the number one album spot recently - but he wasn't too busy to play to fans at St Pancras International in London. 

Taking to the piano, the singer belted out a few songs for passengers-by, who were shocked that they'd managed to catch the performance. 

Watch the clip below: 

Arthur, 35, who won the reality singing show The X Factor in 2012, revealed his shock at getting his second number one album. 

He told PA News Agency: “I’m really emotional about this one, I’ve been locked in a cubicle crying for the last hour.

“Bitter Sweet Love is the official number one album in the UK this week, the best-selling record of the week, which means so much to me.

“It’s been eight years since I last had a number one album, and I’ve been in the game over 10 years.

“I feel like this is symbolic of all the highs and lows; everything we’ve been through.

“There’s no ‘i’ in ‘team’. My management, my label, my friends and family, but most importantly my fans. You made this happen for me.

“I can’t thank you enough for constantly campaigning and supporting; showing up for me.

“My heart is full, thank you very much.”

Bitter Sweet Love has also debuted at number seven on the official vinyl albums chart and is the biggest record on digital downloads this week, according to the Official Charts Company.
