"The World's such a wonderful place" Band of Horses headlining the Main stage. The heavens opened as he sung this line from "Ode to LRC" and it was beautiful!
Little Joe the drummer from Eels introducing himself with a song. (Great set on the Main stage. I think the whole thing is on YouTube)
Sam Lee finishing his set acapella in the middle of the Walled Garden crowd (as he'd run over time and the stage was being cleared for the next act). In traditional folk-club style Sam had us all singing along with the chorus. I could hear the most beautiful voice behind me; sooooo beautiful that I had to turn around at the end of the song to see from where the voice had come and maybe to tell them to consider a career in singing! It was only Rachel Unthank who had played the main stage the night before!!
Me good mate Kraz's Orchestra Baobab t-shirt being spotted by their singer during their set on the main stage last year and subsequently Kraz being filmed onto the big screen
The Melyn Melin set from last year was full of moments. Especially the perfectly timed fly past. And the Ian Dury Cover. I have no idea how they're going to be able to match that on the mountain stage.
And for slugger, here's Little Joe being introduced as the new Eels drummer: www.youtube.com/watch?v=Pcua_F80Shw&t=2919s (but watch the whole set- one of my favourite GM sets despite them not playing very many of my favourite Eels songs)
The proposal at the end of The Big Moon set was pretty special. For me it was Warren Ellis turning to the rest of the Dirty Three and instructing them to "start off slow, then go fuckin' bananas" (in a thick Aussie accent, natch)
I've seen so many amazing performances, but the one's that jump out right now are Swans in Far Out, Neutral Milk Hotel, William Onyeabor and Flaming Lips on Mountain Stage. Mega Faun did a great last set in Walled Garden too I remember. Dexys also.. Ask me tomorrow and I'll 5 different choices.
