I was one of those who got on stage that year, during Angels and Devils. I haven't seen the video for ages but the one I saw skipped Angels and Devils so my moment of infamy is not captured for posterity - BUT I OWN UP - I was one of those that got on stage at Glastonbury '85!!!! Escorted round the back of the stage, told by security if I did it again they would break my legs, then was back right at the front of the stage by the middle of the next song
Apparently Glasto isn't like that now!
