The moment Watford FC fans sailed down the Thames singing their hearts out has been caught on video.

Jack Kelly, 35, originally from Watford, was walking across Tower Bridge with his fiancé at around 1pm on Saturday when by chance he heard the fans chanting from afar.

He filmed the moment a large group of Hornets supporters bellowed songs as they passed underneath the bridge ahead of their away match against Millwall at The Den at 3pm.

Jack, who now lives in Stanmore, said: “It was a good atmosphere and I wish I had filmed it more as the noise got even louder as they went underneath the bridge.”

Other videos shared online show the fans sailing past the Houses of Parliament as they made their way down the Thames.

Watford later lost 1-0 after Dutch midfielder Zian Flemming scored with an early free-kick.

One Hornets supporter commented online: “Game was awful but that boat was something else.”
