Who was John Searing, you ask?
Way back in 1986, John Searing, a die hard Tonight Show fan, starting a massive letter writing campaign. Over the course of a year, he wrote the show expressing a desire to announce and say "Herrrrrre's Johnny!" Over that year period, he apparently sent at least 800 letters, with pictures, begging for the chance. At one point, he got the standard "Thank you for your interest" form letter, but somehow, someway, someone from the show decided that, what the hey, invite Searing to the show and let him have his wish! He got to read the opening intro for the show, and say "Herrrre's Johnny!" and Johnny of course came out from the curtain. After complimenting his announcing, he tells John "Never write us again!"
What does this have to do with game shows? Well, sadly John Searing died in 2015 at the age of 65, and his obituary said he briefly hosted a game show. Would anyone happen to know anything about it? The obit also said after The Tonight Show, he got offers for bit roles in soap operas as well as commercials.
