Here are my top five worst experiences that I can think of:
5) A failed attempt at Marley park was well reported and looked worse than it was. The worst thing about that was one of the security was gabbing me by one of my nipples to pull me out. I told him to let go of my nipple but he refused, so I started to punch the offending arm. He highlighted how the guarda were watching. So, I started shouting, 'Stop assaulting me!' He let go and I ran back into the festival then suddenly he ran after me again and ripped my wristband off to prevent me from getting back into the area in front of the stage. I gave him the finger then leaped the fence into that area. The watching guarda were laughing and the security guy looked like a dick. Hehe.
4) In Cork in 1999 security were on my case before the gig began! Three of them tried to intimidate me by crowding round me and getting right in my face. I refused to hand them my ticket, only allowing to look at it. They didn't believe the seat was mine. During the support band Sack, they stood in front of me for nearly the whole time trying to prevent my view to the stage. They moved their attentions to those who wanted to stand and not sit. Bizarre night!
3) At a concert in Liverpool, 2004, early into the gig after a failed attempt, I was dragged to the foyer and was given a few kicks and punches out of sight of the audience before being thrown into the street. A police car outside drove up and called me over. They didn't care about the assault on me that they saw and did see me booting out at one of the thugs at the end. They just made it clear if I went near the venue, I'd spend the night in the cells. One of Morrissey crew came out to make sure I was all right. He gave me a crew sweater and told me I was not to wear it until the tour was over. I kept my promise.
2) At the Royal concert hall in Glasgow, I jumped onto the on stage speakers from the balcony. Security on the stage put their arms together and told me to jump into them. As I did they withdrew their arms and I crashed onto the stage nearly breaking my legs and wrists. I was then picked up by my belt and given a swift beating all the way to the exit.
1) The worst thing that has happened to me was at Hultsfred. After getting to the stage and reaching up to shake Mozzer hand. Security took me behind the stage and with plastic cable ties around my wrists, they attached me to a metal trolley and held a knife to my throat. They said the police would arrest me but in the end they let me go.
The tours in '91, '92 and '95 were much more chaotic than more recent years but less violent.
A point to note is that the a-holes have always been the venue hired security and not Morrissey's own guys. Even then it is only a small number that are truly out of their depth and result to neanderthal violence.
If you plan on going on stage. I do suggest you read my previous post on the subject linked at the beginning of this post.
