1st Show? Hmmm.
NBC Burbank, March 1987, "Super Password" (w/ 2 unmemorable celebs).
And IIRC as soon as SP was through taping, we went back onto Alameda Ave and got in the line for "Hollywood Squares" w/ Uncle Miltie, The Smothers Brothers, and Charo to name a few.
I have one of the HS eps on tape, but never saw/taped the SP eps as it was never aired in Toledo due to having a noon newscast, and the GSN run still has a ways to go before they rerun it as of last check.
