Tonight, Jack Benny! This is a great one, featuring Mel Blanc as Professor LeBlanc, Benny's violin teacher, and Ronald and Bonita Colman as his next door neighbors. Turn up the treble, the sound is a little murky. "Jack's violin practice drives Ronnie crazy" (4-14-46).
Update: Call Petrillo!
Update II: Listen for Jack's announcement about the USS Saratoga at the end of the program. Maybe newspapers are the first rough draft of history, but radio was the first medium to cover history live.
