Hey Mark! Maybe you're in luck afterall!!!
Seems Ed here just might have been one of those Boomers who actually WERE there droppin' in(err...maybe that should be "droppin' out") there at Yasgur's farm some 38 summers ago, huh?!

(five'll get ya ten he either rode his old Bonnie there or he came with Sunshine Lipchitz in her VW bus)
