Actually, the original person that producers wanted to host the MG '90 pilot, from what I'm told, is Gene Rayburn. But, they found out his age (Damn You ET), and so....
The Host of the Pilot was Bert Convy (To the best of my knowledge, Shaffer *NEVER* did a pilot). In fact, Bert was *Supposed* to host MG '90, but, well, we all know what happened
They needed someone else to host, so they got Shaffer to do it
