Whitney Houston postponed more dates on her European tour due to a respiratory infection. The Manchester Evening News Arena, where Houston was scheduled to perform on April 8-9, released a statement on its website announcing that the two shows had been moved to June 16-17. In addition, her April 11 show in Glasgow has been postponed until May 1. “Doctors visited Whitney late last night in Paris and confirmed that she was suffering from an upper respiratory infection. Upon medical advice Whitney has been advised that she cannot perform to allow her time to recover,” according to the statement. Houston had recently canceled a performance in Paris for a similar health precaution.
