This is a picture of the band Die Hitlers (The Hitlers). It was taken in Düsseldorf, at the Ratinger Hof, in 1980. It appears that the members of Die Hitlers were Markus Oehlen (drums?, also from Deutschland Terzett, Flying Klassenfeind, Mittagspause), Thomas Schwebel (guitar? also in S.Y.P.H, Fehlfarben and Mittagspause), Franz Bielmeier (guitar?, Mittagspause), Peter Hein (Fehlfarben), Jürgen Engler (Male, Die Krupps) and Xao Seffcheque.
But that is about everything I have managed to figure out so far. Good name, though. And I like the Beagle Boy look.
