Music lovers have organized a roll call for those wishing to be among the first to enter the Estadi Olímpic Lluís Companys, with fans of the American rock star having to check in three times a day to keep their spot.

Around 40 concertgoers have already subscribed to the list as of Monday afternoon. The operation started on Thursday, more than a week before the first of two concerts takes place in the Catalan capital.
