I crossed paths with Gregg in the late-90’s. It was about 10:30 A.M., in the Tower Records on Venture Blvd. in Sherman Oaks, California (the same blvd. upon which Tom Petty saw vampires moving west ;-). From across the store’s floor I heard a raspy voice bellow "HEY, LONG HAIR!" I turned around (I was indeed a long hair, the only one in the store), and saw Gregg, leaning against what appeared to be an assistant, who was preventing him from falling on his ass. Gregg was completely smashed, at 10:30 in the morning.
I walked over to him and stuck out my hand, and he reciprocated, his hand shaking mine. He was at a loss for words, so I just said "Nice to meet ya", and turned and walked away. I don’t know if he was already drunk, or still drunk from the night before, not yet having been to bed. I suspect the latter.
