I've never been able to track down where he said it, but my dad reports that he read somewhere that Hannah once said he would've liked to trade his factory works Yamaha for whatever Maico the article was about. There's a lot of hearsay there, and I don't know if it was true or if he was joking or what, but at the very least i sounds like he was impressed.
As an aside, God DAMN that's a good-looking '77.
