Pavarotti too sick to sing

GLASGOW, Scotland, June 29 (UPI) -- Luciano Pavarotti, the 70-year-old Italian tenor, has had to call off dates on his British farewell tour due to illness.

Next Wednesday's concert in Glasgow has been postponed to Nov. 18. Other performances in Chatsworth House, Southampton's Rose Bowl and Warwick Castle may also be rescheduled, the Mirror reported.

Pavarotti has been on a worldwide farewell tour since March 2004. He had planned to retire by his 70th birthday, last October.

The famous tenor is resting in New York. He suffered an infection after back surgery.

"He is deeply disappointed and offers an enormous apology to fans affected," Pavarotti's manager, Terri Robson, said.
