I was at this concert May 23 1976 with Robert Plant and Jimmy Page I had floor seats my friend Susan and I let 2 guys sit with us we sat on there laps and they broke out a joint I was 19 yrs and not really in the drug scene yet so we smoked and I remember the on core but not seeing the faces of them singing the on core songs with them....I never got wasted again in my life, I am 63 and still go to concerts all year long but now by myself...you get orchestra pit seats when you buy just 1 seat...It’s great. I have seen everyone! Hard Rock, Heavy Metal, Classic Rock, Grunge, The new younger guys.
