In honor of Jack Webb's birthday, we'll hear three of the radio and TV legend's old time radio mysteries. First, he stars in a waterfront mystery from Johnny Madero, Pier 23 (originally aired on ABC on June 19, 1947). Then, he's Sgt. Joe Friday on the trail of a killer in "The Big Shirt" from Dragnet (originally aired on NBC on November 30, 1952). Finally, we'll hear a Prohibition-era caper from Pete Kelly's Blues (originally aired on NBC on July 25, 1951).
