The people in the front seating of the Hollywood Bowl were in for a treat on this day in 1954. On stage is Louis Armstrong rehearsing for a live telecast of “The Colgate Comedy Hour” on NBC. He performed an old Rudy Vallee number called “The Whippenproof Song” and maybe those audience members had to sit through it a number of times, but how often did you get to be so close to a master musician like that? You can see the number on YouTube.
