My favorite mock-country song (let me know if you can't find it, because I have it - it's not strictly country, more a country sendup, but it's fabulous) is 'Joy' by Harry Nilsson. Unfortunately most of the country I listen to tends toward country-rock (Eagles, Blue Rodeo, that kind of thing.)
Don't hate Canada, James! We have fries with gravy ... and CHEESE! And much better music than Shania.
... *ponders* I could always make him up a Canadian mix CD, in the interests of saving face for my mother country?
