Sorry to learn of his passing. Actually at one point, all three (Jack Jacobson, Joe Rockhold and Ken Hardin) appeared together in a show that was seen each Saturday at noon beginning in the late 1950's. The one-hour program had a live audience of children who were seated in a gallery. It featured contests, a visit from a representative from the natural history museum, some comedy between the three and even a short "Little Rascals" film toward the end of the program. For a time, there was a segment called, "The Adventures of Nosey & Fertie" inwhich Joe and Ken dealt with some kind of a mystery that continued over the weeks. I'll always remember one of those involved a take-off on the TV show, "The Millionaire". There was a puppet playing the part of Michael Anthony (although he only went by "Mike"). Instead of using the name from the TV show of John Beresford Tipton, Joe Rockhold played a character called "John Bearcat Tip-Top". Actually, this show continued for some years after Jack went to Arizona. I know that because I remember a segment with "Uncle Orrie" and a female guest talking about the University of Dayton meeting UCLA that night in the NCAA championship game and that game was in March, 1967.
I was also glad to see a reference in the obituary to Jack playing "Ignatz Hammerschlob" the host of Your Evening Theatre. That show was on each weekday night after the 11 P.M. news. The set was a door in front of a theatre and he would dress as a doorman and use a German accent to tell what the move was. There was even a sound-effect of traffic played as though you were out in the street. I especially recall a night in August, 1961 when Jack gave updates during that show on the second game of a doubleheader between the Reds and Dodgers being played in Los Angeles. That was when the two teams were battling for the National League pennant. The Reds won both games of that doubleheader, shutting out L.A. in both of the games. By the way, the movie that was featured that night was "Invasion of the Body Snatchers". As you can see, I remember it well.
Even after Jack moved to Arizona, his voice could be heard on TV commercials for a beer. It may have been Bavarian's, but I'm not sure. Those were shown in several cities.
Rest in Peace, Jack. You are well remembered.
