According to NME.com, a fan attending GUNS N' ROSES' concert at London, England's O2 Arena last night (May 31) revealed that he was told to remove his shirt before entering the venue because no one was allowed in wearing merchandise bearing the likeness of the band's former guitarist Slash. NME.com's source then asked security if this was the case and was told by a member of the venue's team, "We were told by the management not to allow anyone into the O2 Arena who is wearing a Slash T-shirt and we are asking anyone who is to remove it, and if they refuse, they will be turned away."Speaking to NME.com today (June 1) about his ordeal, 18-year old James Revell — the fan that was allegedly forced to remove his Slash shirt — described what had happened. He said, "I felt very angry because I was looking after my little brotther at the time and felt as though my freedom to wear what I want had been taken away from me. However, I did not react angrily as I didn't want to spoil the show for him." A photo of the T-shirt in question can be seen below. In January 2010, Fernando Lebeis, the son of Beta Lebeis — GUNS N' ROSES frontman Axl Rose's personal assistant — denied reports that security at GN'R's Winnipeg concert banned fans from wearing Slash gear inside the show. According to TMZ.com, concert security informed fans at the January 13, 2010 show that they were required to turn their Slash t-shirts inside out .... and leave their top hats outside. TMZ.com spoke with a member of the concert security team who "confirmed the marching orders — and told [the web site] the instructions were passed down from a producer for the band." However, Fernando Lebeis denied that any such ban ever took place. Writing on a GN'R message board, he said, "We did not advise any security to ban any sort of apparel.... If they did, they did it on their own accord, or under someone else's order — from within their management."
