Keep in mind that this is in reference to the "World" Tag Titles which were used along with the Southern Tag Titles in the Jarrett Memphis promotion in the early 80s, not to be confused with the CWA Tag Titles which were created in 1988 to go along with the new CWA Heavyweight Title, which unified the Southern, MidAmerican, and International Titles.
The history of the CWA "World" Tag titles is only listed as going up to 1981.

However the titles continued to be used (albeit intermittently) at least until 1983. They ran an angle in 1983 in which two enhancement guys, Robert Reed and Ken Raper, won the titles in a crazy upset. (See link below)

I'm not sure if this needs to be updated right away, in that this isn't exactly the most important item in the world, but there it is anyway.
