Dead Grateful Music

What is your favorite Grateful Dead song? Best Song by The Dead?
I saw Bob Weir and Phil Lesh And Friends. I never really saw Jerry and the Grateful Dead. But, Touch Of Grey, U.S. Blues, The Music Never Stopped, and ShakeDown Street were my favorites.
I even got to see an Encore "Blue Sky" and "SoulShine" by Warren Haynes and Phil Lesh. Beautiful songs that touched me.
Eyes of the world and Wharf Rat
Sugaree also high on my list
