I'm wondering if they didn't film a concert especially for this release may be because of the costs involved. I don't think that Lemmy or the people associated with Motorhead have lots of money left by the end of the tour. Lemmy's lifestyle in particular is quite expensive. When I saw them in Toronto last year the show was sold out but when Lemmy asked how many people in the audience bought Motorizer only about 5 people put their arms up. He then made a joke about everyone else just downloaded it for free.
Also, something interesting that I don't think I mentioned that I just remembered was that there was a white limousine parked near their tourbus. I'm guessing he probably had a busy day doing interviews which the limo had taken him to. It was still parked there a few hours after the show ended. Perhaps if Lemmy hooks up with a girl or girls they use the limo to go to a hotel?
