The one thing I do at any Green Man / EOTR performance, or Bristol gig, is to look to the front right of the stage for a mop of curly blond hair. If Big Jeff isn't there I'm immediately concerned that there may be something better happening elsewhere and that I'm in the wrong place.
Jeff is a walking encyclopedia of musical knowledge as well as one of the loveliest human beings you could ever hope to meet, and has recently taken some tentative steps into sharing his love of music through DJ'ing. In case you haven't seen the Twitter exchange I though it worth flagging here that he's been invited to do a set in the Far Out during Green Man.
I normally pay scant attention to any DJ type activity at GM, but this is one that goes straight onto my not-to-be-missed list. Obviously too late for the printed programme, so watch for updates on Twitter etc.
For anyone not familiar with Jeff this rather old video gives some background - https://vimeo.com/25876003
