Thought it said dikkheads.Any way touch of gray. Do you count Cherry Garcia as a fav?
"Brown Eyed Women"
Sugar Magnolia, Eyes of the World, Box of Rain
Peggy-O........Have you tried archive.org?
Don't know about the radio station, but the music archive of live Dead music is free and amazing.
Probably 'Birdsong' and 'Ripple'.
"Uncle John's Band"
For me it will have to be Chinacat/I know you Rider and Dark Star/El Paso from the 72 Veneta Oregon concert.....utterly insanely cosmic.
