The Who have been forced to postpone the European portion of their 50th anniversary tour.

The first two dates on the tour, scheduled to take place November 26 in Dublin and November 28 in Belfast, have been bumped back to next summer due to "unforeseen logistical changes."

The November 28 Belfast show will now take place June 21, 2015, while the Dublin concert has been rescheduled for June 23.

The tour arrives alongside a new career-spanning compilation, Who Hits 50, which is set for release on October 27.

The double-disc set, which encompasses everything up to the most recent Who LP, 2006's Endless Wire, also includes the new song "Be Lucky."

The band will head stateside starting April 15 in Tampa, Florida, and the tour will keep them busy, criss-crossing the country for the majority of the next year, with the last scheduled date November 4 in Philadelphia.
