On May 26th 1980 The Geils Band played at the PinkPop festival in Holland (Video) & (Audio).
A couple of days before the band got together in London. Seth, DK, J. Stephen and Dick were shocked when they saw Peter with a black eye. Wolf was beaten up by a couple of Irish guys in a London pub because he talked too much.
Thanks to Johan for the following quote from Trouser Press magazine.
Quote: Wolf had gone into a London pub soon after hitting the capital and inadvertently stumbled onto a scene resembling a saloon free-for-all. Wolf wasn’t directly involved but the whole thing spilled out onto the streets and in Wolf’s own words, “the odds were not as beneficial as one might have liked. I mean it had nothing to do with me , but well, when push comes to shove, I don’t like being pushed, so i got in there. When they (United Artists in London) heard about it they said ‘how could you do this Wolf?’ I said @#%$ this, I’m not coming to London to sit in some poofy restaurant, ordering some 1961 Rothschild. I want to be in a pub” When the reporter visited Wolf at his Montcalm hotel his left arm was in a loose sling, he was walking with a limp and his left eye was badly damaged.
