Heh....I've heard the lore of the headband many times. I've heard he used anywhere from 3 to 6 doses of LSD, that used to drip into his eyes. I don't know if any of it is true. Doesn't really matter at this point, but I think it's a cool legend.
And, if it is true, I wouldn't recommend trying it. The LSD back then is a lot different than it is nowadays. I had the opportunity to try some original formula acid a while back. It was called LSD-25, noting that the 25 stood for 25 micrograms of the magickal liquid infused on each tab.
Having tried the original, compared to what's been out there since I've tripped, I concur that the new boss, is not the same as the old boss.
Anyway, that's an entirely different thread. ;)
