I went to a Festi in a field last month. Latitude. It was Grace Jones and the Pet Shop boys, both acts from my youth... Thought it'd be a bit gay.
Grace Jones, who is 60 something and barking mad, did the entire song "Slave to the Rhythm" in the rain, with a hot pink hula hoop. For the entire song. It was not a hologram, she actually hula hooped for 3 or 4 minutes, moving only slightly side and forth. That's a talent, something they don't teach at Uni.
