I'm pretty sure that he was supposed to have pulled a gun on The Ramones (and kept Ronnie Spector confined to the house threatening to kill her if she left him). Strangely enough didn't Joe Meek also pull guns on people in the studio when they couldn't reproduce his ideas properly? Hardly surprising because he was tone deaf and when he hummed his idea it didn't sound anything like what he wanted it to sound - imagine how scary that would be, trying to second guess a lunatic speed freak as he waved a gun in your face. Reminds me of that bit in the Simpsons where Burns orders Smithers at gunpoint to get into a toy plane that's about six inches long.
Actually, in the interest of fairness, I should point out that googling The Ramones story brings up a lot of things saying how it isn't true.
