Love Supreme’s easy-going atmosphere was a treat for all ages, with flower-crowned teenagers mingling with merrily cartwheeling children and older folk in sensible hats and rain jackets.

Backed by harps and strings, Laura Mvula radiated a calm joy: her set picked up momentum as Green Garden segued into See Line Woman. As light raindrops speckled the crowd, a forest of cagoule hoods and umbrellas bobbed up and down.

Lalah Hathaway’s meandering slow jams on Summertime and Angel were soft and atmospheric, with her appreciative audience nodding along.

The Earth, Wind and Fire Experience’s three frontmen shimmied enthusiastically in sparkling silver shirts to classics like Shining Star and September, but there was nothing new about this slice of the 70s.

In contrast, Jamie Cullum bounded on stage energetically, drumsticks in hand, compulsively moving. Whether whacking the cowbells, beatboxing, drumming with his hands, or striding atop the piano and leaping around the stage his jubilant excitement was irresistible.

He stalked along the front row to a throbbing, sleazy, bass-heavy version of Love For Sale, and wove together snatches of Justin Timberlake and Michael Jackson with I Could Have Danced All Night, before improvising a song about Love Supreme, to the audience’s delight.
