I was - and still am - a classical musician, and I had never been to a 'rock' show before,. I knew nothing of the Grateful Dead or their music, except I had heard snatches of Truckin on the radio, and was waiting to hear if they would play the little bit of what I was familiar with. Despite the effects of 'refreshments' handed down from the stage before the show - which might account for the universal uncertainty about the second set set-list - I immediately recognized the tune when it first arrived. At that point, the band was sailing through one song into another and totally blowing my mind - I thought I was listening to Mahler or Bruckner, but on a different planet. Truckin came and went two or three times amidst other unfamiliar but compelling tunes, and I came away a Deadhead-for-Life! A few years ago, a recording of Dark Star>Eyes>China Cat from the show came my way, and any doubts I had that my reaction was induced solely by the the little tab of paper I ingested were put to rest. My mind was blown anew, without even the assistance of a dose of prescription strength red wine (I'm older now....). I also remember songs with references to 'wine' in them: We can share the women/wine, red grenadine, etc. I'd love to connect with anyone else who was at this amazing show....viva '73!!!
