I've had this excerpt of the Grateful Dead song "St. Stephen" at the end of a cassette since I was
in high school:

It is clearly from a vinyl source (someone made the tape for me and stuck this on the end, knowing
that I didn't like the Dead in those days, this was an attempt to change my mind).

I'd like to know the source so I can listen to the whole album or concert recording. This recording
is somewhat distinct because of the guitar feedback at the beginning and the goofy organ riffs
throughout (I'm guessing Pigpen was the source). I consider it a good performance overall because
the vocal harmonies were better (more in-tune) than most other live recordings of this song that I
have heard.

More info about the recording much appreciated.
