I initially thought I had come across an extremely interesting item currently on ebay is this recording (my first impression was that this was previously completely unknown to me)
the flipside is one of the singles tracks on "Early Lightfoot"
that I know pretty well already

I must have missed it because it certainly appears on Wayne's cornucopia
http://www.lightfoot.ca/single60.htm
(albeit as an alternative or more complete song title for Adios Adios
but I gave never seen it on sale before under that title although I have of course heard Adios Adios.
and the title does indeed appear in the first line of the song as evidenced by:-

"G) I'll meet you in Mich(C)oacan the (G) heart of Mexi(G7)c"
Phew!!
