The Baby singer caused chaos in the northern England city when hundreds of screaming fans fought to get a glimpse of their idol after he checked into the Hard Days Night Hotel on Thursday, in a scene that was reminiscent of the hoards of fans that gathered in Liverpool during the height of Beatlemania in the 1960’s.
