Turns out drummer Jon Brookes has a longstanding shoulder problem and doctors told him that drumming all those shows could cause further complications.

From the band’s Web site:

“The Charlatans are sorry to announce the cancellation of their forthcoming North American tour. This is due to drummer Jon Brookes’ longstanding shoulder complaint. He has been strongly advised by doctors against undertaking 23 concerts in 28 days as this could cause severe damage to ligaments in the affected area. He will start a course of treatment starting in September and in the coming months to rectify the condition.

“Once again the band wish to apologise to people who have purchased tickets and those that had made travel arrangements We are as disappointed as you are, due to this unavoidable situation.

“Many thanks.”

The tour was scheduled to begin Sept. 17 in San Diego. At this time the band is still planning on playing two upcoming U.K. dates – the in Aberdeenshire Aug. 29 and the in West Cumbria Aug. 30.
