I'm a total beginner in singing and I'd like to learn to sing this song with two friends: I Know You Rider by the Grateful Dead. There should be three voices (Jerry, Bobby and Phil), but I'm not even sure of that. Specifically I'm interested in the the part that is quite clear from 9:53 to 10:04 in this live version:
Grateful Dead - China Cat Sunflower / I Know You Rider (5-3-72)
If someone more skilled could tell me the number of voices, and at least maybe the starting points, i.e. the first two or three notes of each voice, that would be a huge help!
