Boy, whenever the boys started to drift into Dark Star, I just had to duck out.
IMHO, this question deserves nothing more than such a sarcastic, ridiculous response.
Maybe my view is distorted because I stopped seeing shows in about 1983. Did things get so bad that "just about everybody" had at least one song they despised hearing? I recall there were some songs that I didn't love, and after hearing 40 or 50 "drums," I sometimes got a little bored, but never did me or any of my group of deadheads want to be anyplace else. Wow.
But to each their own!!!
Anyhoo to answer the question:
For years, I really didnt have one, wanted to see and hear EVERYTHING. Every little note in Minglewood, Rooster, Des Row, CC Rider, Push, Walkin Blues..you name it, I would not miss it. Even Day Job~~~~
Drumz when I could hold no longer...but really it was the intro of songs like
Wave to the Wind & Corrina when I decided...oh man, pee break songs.
“The Omnipotent Grateful Dead!”
Don't get me wrong, I used to dig watching them beat the tar out of the skins, but it was an opportune time in my opinion for a piss and a beer or whatever.
I would often leave for the same reasons during a first-set FOTD, CC Rider, Minglewood, Jack a Roe, Me and My Uncle, Mexicali. Only if need be, mind you.
I (we'd) also leave the show early if Day Job notes were struck for the encore to beat the squeeze out to the lot.
For me, since I started going to shows only in '93... it would be Easy Answers. I've been to a bunch of shows but unfortunately had to see this one too many times. I would probably have to say the same for Eternity and for Way To Go Home.
Sorry Gans (who gives me shit about that) but I know I'm not alone here! There's a little giggle story about that associated with this year's KPFA GD Marathon.
I think Estimated might have been a pee song sometimes, too. but never, ever out of the hall for Stella Blue, Mexicali Blues, or anything that featured Brent.
