Back in the early 1970's we had a old brother named Harry Campbell. He use to talk about Rutherford all the time. He knew him very will. He claims he help develop the soundcars. He would talk about driving these soundcars all over the place. He would laugh about waking people up in the morning with the loud sounds coming out of the speakers. Harry was in his mid 80's when I knew him and this experience was the highlight of his life. He never said anything bad about Rutherford except he did not like the ending of using soundcars.
Back in the 70's I knew a lot of the old timers that Russell and Rutherford real well. Most were positive about Russell but very negative about Rutherford. Still Totally ADD
