"Jeff Regan, Investigator" is a Jack Webb series that just predates "Dragnet." This P.I. has an even drier delivery than Detective Friday, but he's much more sarcastically verbose. In tonight's episode, movie cowboys and racehorses get entangled in a big-money scam. Then on "The Jack Benny Program," Jack goes into Beverly Hills to try to buy a new violin string and ends up getting a parking ticket.
