Similar verse but the riff is far and away cooler than abracadabra and for that reason sets it apart for me. Plus seeing fast times when it was new put a soft spot in me. Killer song

I'm just a shitty drummer who cant sleep and know nothing about the laws regarding this situation. But the legal advise I'd give is, if your song/video blows up and makes money, then he finds out, he might try to get some of that money. If his own words are defamatory toward himself, are You defaming? Sounds like it could be some good art. Good luck
