Where and when: West Holts stage, Saturday 4.15pm.

Dress code: Ray-Bans and skinny jeans for Mr Banhart, who today is looking more alt-hipster than folkie-hippy. He's also sporting a T-shirt that looks suspiciously like an item of vintage MC Hammer merchandise. If so, it's absolutely in keeping with a gleefully ironic set.

What happened: With a jaunty "bonjour!" to the crowd, Banhart leaps onstage to introduce his band, the Grogs, and give us a bit of skittish rambling about being here not to play music but to debate politics and the economy. Such a tease! There follows a playful set, with much campy, spasmodic dancing from the man himself that is at its finest during 16th & Valencia Roxy Music, his tribute to "a little band you probably haven't heard of, I think they're going to be big someday". He ends with what must be – certainly in terms of sentiment – his signature track: I Feel Just Like a Child pretty much sums up this 29-going-on-9-year-old and, as the crowd stomps along with infantile abandon, it looks like he ain't the only one.

Who's watching: A massive, sun-woozy crowd, which includes several ingenious shade-casting mechanisms but even more scorched bare flesh. Robust wafts of marijuana sweep through the lot.

High point: A cover of Taylor Dayne's gloriously naff dance-pop 1987 hit, Tell It to My Heart, which he ends by yelling, "That's for my mom!", adding, "Do you love your mom?". The answer is a big affirmative roar of mother-love.

Low point: His inexplicable forary off stage and into the audience, leaving a few minutes where everyone but the first two rows of crowd clueless as to what was going on.

In a tweet: Giddy grooves on a perfect summer afternoon from freak-folk's irrepressible man-child.
