When and Wherefore:
MG's could feasilbly be from any of the runs GSN has, WML is from 1955 (the only year given at any point in the bit about the marathon), Password is from early on in the Nighttime run, assumedly...All that was stated about Password Plus is that it was from before Allen's death - whether that means it'll be an episode from the Ludden run prior to illness sidelining Allen in 1980, or a Kennedy-era episode from 80-81 is unclear from the article.
No info given on the timeframe for Tattletales, To Tell the Truth, or Body Language, though TTTT will probably be the 1990 version, given the fact that it's the one GSN's currently running, and she appeared with high frequency therein.
*Please Note: TTTT version is an inferrance based on the things mentioned following the word given, and is subject to...well...being wrong.
