The entirety of Ween’s 12 Golden Country Greats is amazing, especially since they hired Nashville session musicians to make it genuine. Also there are some David Allan Coe songs that might fit the bill, but I wouldn’t dare even mention their titles.
With Hitchcock you’re never entirely sure he’s joking, but I think this is a parody (it might be a parody of the Stones doing a country song): Robyn Hitchcock - Ye Sleepimg Knights Of Jesus
Zappa’s unreleased Falling In Love Is a Stupid Habit which can be found on You Tube. Asylum Street Spankers - Hick Hop the Sensational Alex Harvey Band - Shake That Thing with the Come a Tie Yay Yippie Yay Yea out chorus
more Homer & Jethro, best part of the joke was that Jethro Burns could play circles around pretty much anyone.
You could never be sure if it was a parody with these guys, part 2: trying to find the studio version but couldn't jb
