Richard Wagner (1813-1883) was a contemporary of "Mad" King Ludwig II, builder of Neuschwanstein, and having been deceased before young Adolf's birth was related to Nazism only by the word "Deutschland."
I don't hold The Beatles responsible for Sharon Tate's murder, but one cannot disassociate Manson with "Helter Skelter."
But an even better Wagner quote is Mark Twain's "Wagner's music is better than it sounds." No idea if it is real but I picked up a few viruses investigating.
Wagner was notoriously anti-Semitic, though I can't see how he could be charged with influencing Naziism. Europe already had centuries of evil thinking, which were of far greater influence.
That said, the second-best gift I ever gave my old man (exceeded only by the big box of Scotch and beer that turned out to be his last Father's Day gift) was a full set of The Ring, conducted by Georg Solti (look him up to see his original name, which is a pretty obvious clue to his family's religion).
Generally, a good rule of thumb is "anytime you're quoting Twain or Samuel Johnson, your quote will be proven bogus." I really thought I had it that time, thanks for proving my rule.
Awesome Father's Day gift PE. I hope it was his latest such gift, however, rather than his last.
