According to AMG - All Music Guide, SUPERMARKET WINE performed by Mickey MacConnell is included on the various-artists compilation "Celtic Traditions: Memorable Tales," Celtic Tales CD 4618, 1998.

A sound sample at Barnes & Noble contains these lyrics:

...always seemed to rain
And it's then that I'd discover
You'd forgot the pegs again
And I couldn't get that campfire lit
Now matter what I tried.
Don't you remember?
We'd had roadside stops for bread and cheese
And supermarket wine....

Looks like this is the same Mickey MacConnell who posts at Mudcat under the name chordstrangler.

Looks like his name is often misspelled, at Mudcat anyway, as "McConnell."

And Ragman, what do you mean by the "Smokie image"?
