The band were forced to cut short their performance at Germany’s Wacken Open Air festival last night due to Lemmy’s health. Since then, organisers of the festival have issued an official statement:

“Motörhead rocked the Black Stage for more than 30 minutes and Lemmy gave everything he´s got to play an amazing live show,” they said. He´s keeping well – but the temperatures and circumstances led to the point that continuing the show would have led to a loss of quality. We are very happy and proud that Phil, Mikkey and particularly Mr. Rock n’ Roll himself, Lemmy Kilmister, played W:O:A 2013 and that they did everything humanly possible to play this gig. Thank you so much, guys!”

Motörhead had to stop after six songs after Lemmy was unable to continue. In June it was revealed that he had a defibrilator to correct heart problems, and suffered a haematoma shortly after. The band have cancelled tour dates in November but are still planning on releasing their new album, Aftershock, in September.
