The difference between the Rewind Festival and others on the summer scene is the number of lines on the faces in the audience.
Looking around, the crowds stood in either the very well mannered mosh pit while others sat in their fold up chairs surrounding waterproof picnic blankets, as people apologised as they tipped toed around seats or nudged each other elbows as they carried drinks.
But it is their one and only chance of the year to delve into the back of wardrobes to pull out dungarees, hair bands and 'relax' T-shirts to reminisce about the best days of their lives.
If they didn't have it in their wardrobes there is now a fashion machine surrounding the 1980s and there were lots of new white Choose Life T-shirts, a la Wham.
Henley Festival stalwart and nearby resident Carol Decker roared out Heart and Soul and iconic China in your Hand on Sunday afternoon was when the audience knew that these old timers, most of whom are now in the fifties, still have it.
Watching Midge Ure I was stood in awe of this man who I had only seen on tele as a child growing up through his close links to Band Aid and Bob Geldof still being able to produce his Vienna voice with aplomb.
The Selecter whipped up the crowd with their ska and Nik Kershaw was understated but still the man with the big hair and the tunes that I grew up with and the irony was not lost as he sang "I won't let the sun go down on me" as the sun set over Henley. He was the only one brave enough to have a video from his youth playing in the background as he sang.
Bananrama looked amazing and were enjoying their time on stage again as the crowd belted out Venus, and Robert De Niro's waiting complete with dance moves as they waited in a cocktail bar for the finale of the Human League.
But it's not just about the music, however, or the roller disco, silent disco or the very good side stages of bands pumping out other 80s classic like Queen.
It is about people celebrating the much maligned decade, the dress sense, the iconic cartoon characters, games and films and pressing play and record on as they tried to make mixed tapes from the top 40 on a Sunday night.
So that it is not surprising that when waiting in the long lines for the loos or bar to turn around and see An Officer and a Gentlemen, Top Gun pilots, Dick Dastardly, Ghostbusters or CHiPs among the Madonnas and lurid florescent clothing that made the 80s so good.
