The Vaccines performed at Venue Cymru in Wales on Monday, May 6, but several fans have now come forward and told the press that they were denied entry to the show after not being able to answer questions about the band.

Andy Bellis (shown left) told Wales Online that when he went to pick up his tickets from the door, he and a few others were pulled to one side and asked trivia style questions about the rockers, but because he couldn't answer them he wasn't allowed into the venue:

"We queued up for a good half hour and give our tickets at the door. It seemed pretty normal. So, we’re pulled aside to get searched and the security guy asks if I know the lead singer and could I name their two albums and some songs."

"I couldn’t think off the top of my head so they kicked us out, took the tickets off us and said we couldn’t watch the band because we didn’t know enough information about them. I’ve made a complaint to the venue asking for a refund as there was no other reason I wasn’t allowed in."

Venue Cymru has since issued a statement, admitted that people were searched before the gig due to the risk of 'pickpockets', but no one seems to know anything about the general knowledge questions issue:

"Venue Cymru was made aware that pickpockets may attempt to operate in the arena during The Vaccines gig. In order to ensure the safety and security of our customers we carried out random checks of those in the queue. As a result six people were refused admission and a further two people were ejected from the building."

"Security were working closely with the police and licensing officers throughout the evening. Unfortunately one or two genuine visitors may have been refused admission and we apologise that they missed the event and full refunds are being given."
