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."
