Train passenger proposes to girlfriend with choir - video

A London man has proposed to his girlfriend on a packed commuter train with the help of a 25-strong choir.

Singer Adam King organised for his choir to serenade Lucy Rogers with Bill Withers classic 'Lovely Day' on a train from London Euston on November 1, popping up at the end of the chorus to pop the question.

"When someone started singing I thought, 'That's great, what a lovely train journey I'm on, it must be a flash mob'," Rogers told Sky News. "And then when he got down on one knee, it was only at that point that I realised it was all for me."

King revealed that he had been planning the proposal since April and even built a replica train carriage to work out the logistics of his big moment.

He was forced to take drastic action when Rogers announced that she would be driving to work on the day in question, disconnecting her car battery to stop his plans being thwarted.

The couple have said that they are considering holding their wedding on a mode of public transport.
