I actually made an adjusted version of the first few seconds of the Beatles' "Don't Bother Me", which has an incredibly flat note sung by George Harrison. I fixed it, just to hear what it would sound like with him perfectly on pitch. Sounded pretty good. Then I deleted the project, consigning this obscenity to the flames of history. But this was OK. I waited 50+ years to hear that, as a loyal fan I earned the right to have that experience just once in my lifetime.
