This was the hilarious moment a commuter on the London Underground was spotted singing his heart out to the Bon Jovi classic "Livin' on a Prayer" yesterday (October 17).

Footage shows the vocalist facing away from other commuters while performing the anthem.

The filmer said: "[I was] on my usual commute from London to Wiltshire this happened!

"I heard the singing from the platform and then when I boarded the train the guy started again!

"He sang a number of songs by Bon Jovi and Aerosmith.

"He had real heart, he faced away from commuters and was clearly having a great time."

"He made my day, [it was] such a wonderful way of brightening up the tube journey."

"When he finished his songs he gave me a thumbs up and left the tube.

"It was on the Hammersmith and City line and a few people have commented on twitter that he has done it before."

On my usual commute from London to Wiltshire this happened! I heard the singing from the platform and then when I boarded the train the guy started again! He sang a number of songs by Bon Jovi and Aerosmith. He had real heart. He faced away from commuters and was clearly having a great time. He made my day. Such a wonderful way of brightening up the tube journey. When he finished his songs he gave me a thumbs up and left the tube. It was on a the Hammersmith and city line and a few people have commented on twitter that he has done it before. It was on Thursday 17th October around 5pm.
