The eagerly awaited concert by Colombian star Shakira did not take place at Santo Domingo’s Quisqueya Stadium last night (Thursday) as hoped. The singer was originally scheduled to perform on Wednesday, however, on the advice of her doctors, promoters are telling ticket-holders that the concert will be postponed till 22 May. This is the first time that Shakira has had to cancel a performance, and according to Diario Libre, her appearance in Puerto Rico on Saturday is also uncertain, unless her flu improves.
