With more than 3,700 seats and at 1km long, it was one of the UK's longest street parties - and a spot of rain certainly wasn't going to spoil the fun.
The villages of Goring and Streatley, separated by the Thames and in two different counties, joined together in spectacular style to celebrate the Diamond Jubilee with 465 trestle tables spanning the two high streets and the river bridge.
Red, white and blue ponchos were the order of the day, with the streets transformed into a sea of umbrellas as the heavens opened just as the party got under way.
Free scones, with strawberry jam and cream, were made at local pub The Miller of Mansfield and were distributed to everyone sitting out in the wet weather on tables stretching from The Bull pub in Streatley, Berkshire, to the railway bridge in Goring, Oxfordshire.
Local musicians provided the entertainment, with a Queen Victoria and Henry VII providing a regal touch.
The 1km stretch was decorated with red, white and blue bow ties, made to celebrate the links between the two villages.
Organiser Ron Bridle, part of a committee that had been planning the celebrations since last July, said: "We've never had anything like this before. The two villages have a combined population of 3,720 tickets - but there are many more than that here as not everyone has a seat.
"It's fantastic to see all of our plans come to fruition. It's been absolutely wonderful."
The villages' celebrations will continue with an evening variety show ahead of their own version of the river pageant tomorrow - a sail-past of colourful boats - and a torchlight procession, before the lighting of the Jubilee beacon which is also tomorrow.
