Oh, the Scorpions weren't always in good taste, no doubt, but that's a classless affliction worldwide. Moustaches were ok in the 70ies, especially the one Rudi Schenker wore, was pretty standard if a bit naff. And when Virgin Killer came out in Germany, no one thought much of it, it was a cover with a naked girl, so what. It only became an issue decades later. At the time, no one thought the Scorps had turned pedophile.
