Noel Gallagher performed the encore to end all encores as his High Flying Birds brought Festival No 6 to a spectacular close.
When the former Oasis frontman said goodnight after performing his classic B side The Masterplan about an hour into his set the sodden thousands who stayed to the bitter of end of a horrible two days of weather chanted for more.
His wry smile as he walked off the main Festival No 6 stage hinted that they might not be disappointed.
He'd played a few classics from his extensive back catalogue with Liam and the boys and the High Flying Birds including; Champagne Supernova, Half a World Away - another gem a B side - and High AKA..What a Life.
But no Wonderwall we'd get that right?
Well we did, but before that he pulled the most spectacular rabbit out of his hat.
After leaving the crowd on tenterhooks for what seemed like an age he walked back on stage to a deafening roar.
He said: "I don't f''ing believe I'm about to say this: Paul Weller's going to join me on stage."
The place went mental as the Mod God strolled on in immaculate box fresh white sneakers.
I've no idea how he kept them so clean in the mudbath that was Portmeirion.
Paul took centre stage, with Noel providing backing vocals for the Jam classic Pretty Green.
Next up, a Town Called Malice cue bedlam.
And with that, after a polite goodbye and kiss on the back of the neck for Noel he was gone.
I don't think any of the 10,000 or so could quite believe what they just witnessed.
But it didn't end there.
Noel said simply: "Wonderwall - you sing it." And the crowd duly obliged.
He wrapped up with Don't Look Back Anger and as the song came to a close the Festival No 6 organisers released giant white balloons into the crowd in homage to The Prisoner, filmed of course at Portmeirion.
There wasn't a dry eye, a dry anything at that stage as the rain just kept pouring down.
Despite the weather and the chaos it caused at the park and ride the music and entertainment at Festival No 6 is first class and we should never forget that.
