Guns N' Roses fans were told to remove their Slash t-shirts or go home before his London appearance last Friday.
Perhaps it's no wonder that fans were throwing pint glasses at the band before the end of the show.
One fan, James Revell, has explained that he went to the GN'R show with his younger brother, but staff at the door said they would refuse him entry if he didn't remove his Slash t-shirt.
"I felt as though my freedom to wear what I want had been taken away from me,
" James told NME
. "I did not react angrily as I didn't want to spoil the show for my brother.
"I believed they asked me to do it because Axl Rose has some problem with Slash, and if he saw me wearing the shirt he might have stormed off stage."
After all that, James and his brother had to leave after only three songs because the band started 50 minutes late - which, as we know after last week's expose, the band might plan in advance. At least they weren't more than an hour and a half late, as they were the previous night.
Karma kicked back at the band when fans started to throw glasses and money at the stage, prompting bassist Tommy Stinson to warn the crowd that they would cancel the rest of the show if it continued.
