Families can enjoy a day filled with fun and music in the picturesque setting of Strawberry Hill House.
Twickenham band the Carnabys, who won the largest global battle of the bans contest, Hard Rock Rising, will perform on the music stage later in the afternoon.
The stage will provide guests with live music all day including The Deputies, funk rocker Alix Anthony and 50s toe-tapper Nark Drool.
Children can take part in pony rides, water zorbers and enjoy fun at the fairground.
The afternoon, sponsored by the Rugby Football Union, will see guests glug Pimm’s in a large booze tent and munch on grub from a plethora of food stalls.
All money raised during the afternoon will support Strawberry Hill House.
