Guitarist SLASH (ex-GUNS N' ROSES) has posted the following message via Twitter:

"Visited Lemmy (Kilmister, MOTÖRHEAD) today; he's doing well. There's been a lot of rumors. But he's in good shape and finishing Motörhead record now."

Lemmy walked offstage on August 2nd six songs into the band's set at the famous Wacken Open Air being held in Wacken, Germany, due to health reasons.

A band statement reads: "The show had to go on because that's how Lemmy rolls. Even though he was not 100% fit, he refused to feel he was letting the 85,000 Wacken fans down. They kicked ass in the 100-plus degree heat for a shortened, but powerful, set before, Lemmy finally realized he might have bitten off a little more than he could chew. Thus he will embark upon the recuperation recommended. We know that rumors are flying around, but once he fully recharges, Motörhead will be back, don't you worry!"

Pro-shot footage of the band's W:O:A set can be seen below:

Lemmy's departure from the stage was disturbing given the fact that the legendary three-piece had cancelled all of their summer shows due to their frontman's ongoing health issues; in June doctors ordered Lemmy off the road to recover from a hematoma he suffered that month. According to BraveWords staff who were at the scene, on-stage he even referenced the doctors orders saying that he had to quit, but responded 'We'll have to see about that."

With tongue-in-cheek, Motörhead kicked-off their set in front of nearly 100,000 people with 'I Know How To Die', but witnesses - including BraveWords who were backstage - saw that the legendary frontman was not in his usual form. The band stormed on with 'Damage Case', 'Stay Clean', but the set was cut short during their classic 'The Chase Is Better Than The Catch' as Lemmy walked off stage and Phil Campbell took charge until everything went black.

Wacken organizer Thomas Jensen walked on stage and told the crowd (translated from German) … "Lemmy had cancelled all his dates and tried to do Wacken, but this is all he could do."

The Wacken crew have since issued the following statement: "Motörhead rocked the Black Stage for more than 30 minutes and Lemmy gave everything he´s got to play an amazing live show. He´s keeping well - but the temperatures and circumstances lead to the point that continuing the show would have lead 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 were scheduled to perform for an hour and fifteen minutes. After Jensen's announcement the crowd starting chanting "Lemmy, Lemmy, Lemmy."

The crowd was not upset or disappointed, but concerned for one of the godfathers of heavy metal.

DORO PESCH followed kicking off her 30th Anniversary tour, but made a point in stating to the crowd that "Lemmy was ok."
