Guns N' Roses' tour of the United Kingdom continues to be something other than a good will mission. Earlier in the week, they angered fans in Manchester by taking the stage an hour later than expected. Now comes the news that, during their first of two shows at London's O2 Arena on Thursday (May 31), security refused entry to a fan until he removed his Slash t-shirt.

James Revell, an 18-year old fan, told NME that his choice of clothing was unwelcome in the large venue. "I felt very angry because I was looking after my little brother at the time and felt as though my freedom to wear what I want had been taken away from me," he said. "However, I did not react angrily as I didn't want to spoil the show for him."

According to a member of the arena's security staff, the directive came from the band. "We were told by the management not to allow anyone into the O2 Arena who is wearing a Slash T-shirt," the guard said. "And we are asking anyone who is to remove it and if they refuse they will be turned away."

To make matters worse, another delay by Guns N' Roses meant that Revell and his brother only got to see three songs before having to catch the last train home. As such, he missed the surprise guest appearance by former Guns N' Roses guitarist Izzy Stradlin.

It's one thing when ex-bandmates get into a war of words, but you know it has probably gone too far when it turns into a war of clothing.
