Just days after The Human League pulled out of this summer’s planned Regeneration Tour saying the group had been “promised one thing and delivered something so completely different,” another act on the bill, Erasure frontman Andy Bell, is warning fans that he might not be joining the tour, either.

The Regeneration Tour, which bills itself as “North America’s premier ’80s tour,” has lost another high-profile act, as The Human League this week pulled out of the summer trek, announcing “we were promised one thing and delivered something so completely different we just could not make it work, much as we wanted to.”

Billing itself as “North America’s premier ’80s tour,” the semi-annual Regeneration Tour returns this August for an undisclosed number of U.S. concerts featuring Erasure frontman Andy Bell, The Human League, Howard Jones and Information Society — but not, as tour promoters originally had hoped, the reunited Ultravox.

Erasure on Friday will announced and put on sale a limited-edition collectors’ box set called ‘The Complete Tomorrow’s World,’ a release that caps off the promotion cycle of the band’s 2011 album by collecting commercially unavailable tracks and mixes, plus all of the promotional videos made for the record’s singles.

With the less than a week to go before the release of their 14th album, Erasure are letting fans listen to ‘Tomorrow’s World’ in its entirety via a stream posted Tuesday by The Guardian. The full album arrives Oct. 3 in the U.K. and Oct. 4 in the U.S.

Erasure today announced the completion of ‘Tomorrow’s World,’ the group’s first new record in four years, which will arrive this fall on Mute Records and be accompanied by a 25-date North American tour.
