The only outdoor festival in Britain where the Wellingtons may well be on the guest-list.

When one thinks of a posh festival, does one think of glamping at Glasto? Think again. Our very favourite upper crust festival is none other than Henley. Handily located down the road (for our London-based readers at least) Henley is all black tie, fine dining, lashings of champers and skies full of fireworks. Now that’s what we call raving.

From 10th-14th July, Henley-on-Thames will see the likes of Madness, The Beach Boys and local heroine to all aspiring fashionable toffs, Paloma Faith take over the worryingly-named Floating Stage. If the talent doesn’t bob off towards the North Sea, everyone’s favourite sexational sexagenarian Joanna Lumley will be hosting ‘Shaken & Stirred’, a collection of Bond themes by the London Philharmonic Orchestra.

The best thing about the whole event? Aside from the Lionel Richie-approved all night-long parties, the fact that the festival is actually a not-for-profit organisation is to be admired. Every single penny made will go directly to the Henley Festival Trust, who finance projects to inspire and transform the lives of talented and underprivileged young people. Party on, chaps!
