Hi Mat,
Would you be please so kind to re-post these two 1966 shows:
Grateful Dead – Unknown Location (xx/xx/66) (Grateful Dead Hour no. 557)
Grateful Dead – Unknown Location (??/??/66) (Note: Often labelled “2/66,” the actual date is unknown)
Thank you for giving us these old gems.
Bill

I think this is what you are looking for. I’ll redo the actual posts later but this should get you the music.
Great!
Thank you!
