(Walk Me Out in the) Morning Dew - Grateful Dead
I've been waiting for someone to post the 1967 studio version (which I don't own), and at LONG LAST, here it is. As you might guess, the live versions can run a whole day at a time. ;)
This song opened the Human Be-In in 67, and was then recorded by the Dead two months later, on their first album. (I think the sweet, childlike hope of the times really shines through on the original.)
Enjoy!
