British rockers the Arctic Monkeys have been forced to scrap two shows on their current U.K. tour to allow frontman Alex Turner time to recover from laryngitis. The band postponed a Halloween night gig in Birmingham, England following the singer's diagnosis, and the concert was just hours after he performed at the Mercury Prize awards ceremony in London. A second show in Glasgow, Scotland scheduled for Friday (01Nov13) has also been axed. A statement from the band reads: "We wish to apologise to all ticket holders for any inconvenience this has caused." The two scrapped gigs will now take place on 20 and 21 November (13).
