A copy of the original (?) United Artists issue of "Spin Spin' is on Ebay right now from a Torontonian who says in his sales pitch
"The most difficult Gordon Lightfoot 7" there is to locate
Very Early release on United Artist 1965-66
GORDON LIGHTFOOT
SIDE A = Spin, Spin (MINT)
SIDE B = For Lovin Me (MINT)"
Note that I always assumed that Underground Records who reissued Spin Spin b/w Just Like Tom Thumb’s blues was a specialist golden oldies outfit, I bought a copy that has since cracked and thus become unplayable in Ottawa in 1989.
