Love and carriage! Groom-to-be becomes internet hit as he gets down on one knee on the 19.57 to Watford

Think of perfect places for a marriage proposal and the 19.57 to Watford Junction is unlikely to be what springs to mind.

But with a little help from a show choir and some very careful planning, tailor Adam King transformed it into the most romantic of locations to pop the question on Tuesday evening.

And, happily, his girlfriend Lucy Rogers said yes. Miss Rogers, 25, had rushed to catch the packed train after having dinner with friends.

Shortly after it pulled out of London Euston, she and the rest of the commuters on board were left stunned when the choir broke into song.

And it was halfway through their rendition of Bill Withers's hit Lovely Day that Mr King got down on one knee. A video of the proposal – complete with a romantic opening sequence – has since become a hit on YouTube.

Mr King, 34, who started planning it in April, enlisted the help of the Adam Street Singers, a show choir of which he is a member.

They spent weeks rehearsing the song, even building a recreation of the carriage to practise the proposal.

But Mr King said: 'The biggest problem was making sure Lucy made the train.'

The scheme almost fell apart, when Miss Rogers decided at the last minute on Tuesday that she wanted to drive instead of taking the train.

Keen not to let his plan collapse, though, Mr King disconnected the car battery to make sure she would be on board. He said he and Miss Rogers had not thought about wedding plans – but added: 'I guess the pressure is on to make it memorable now.'
