Cher [ tickets ], whose North American farewell tour is now in its fourth calendar year, will play several shows this spring to make good on some concerts she postponed due to illness in December.

The singer has rescheduled her appearance at Montreal's Bell Centre for April 7; her show at London, Ontario's Labatt Centre for April 10; and her appearance at Connecticut's Mohegan Sun Arena for April 12.

The outing is currently expected to conclude with an April 13 concert at Continental Airlines Arena in East Rutherford, NJ, which was rescheduled from Dec. 9.

Cher previously announced that she would end her outing--now dubbed the "Never Can Say Goodbye" tour--with a series of international dates, concluding with a March 11 show in Brisbane, Australia.

The tour launched in June of 2002, and was initially scheduled to visit fewer than 50 North American cities. She's since added well over 200 dates to the run.

At Cher's performances, concertgoers can expect to hear songs culled from throughout her four-decade-long career, and to see her make multiple costume changes.
