Scotty's Music Store tape -- 10/72 or 5/14/70?

[Jim Powell]

Paul Gibian just passed me a CD copy of the tape of Jerry, Bob & members of
NRPS in Scottie's Music Store in St. Louis, fiddling around & playing

Dim Lights Thick Smoke jam
Country Roads
instrumental
Long Black Veil
another tune
Green Green Grass Of Home


My old copy of this tape is labeled "10/17-19/72".  This new copy is labeled
"5/14/70."

Can someone fill in details on the question of dating this tape?

Also, should it be spelled "Scotty's" or "Scottie's"?
