A groom's elaborate proposal on the 19:57 to Watford Junction has become a YouTube hit.
Adam King enlisted the help of his choir, the Adam Street Singers, to serenade his girlfriend, Lucy Rogers, with a rendition of Bill Withers' Lovely Day.
The 34-year-old tailor then asked Miss Rogers, 25, to marry him.
A YouTube video of the proposal, which has now gone viral, shows the groom-to-be getting down on one knee on board the 19.57 London overground service to Watford Junction, before Miss Rogers says...well you'll have to watch and find out!
