I remember Big Bill Campbell's Rocky Mountain Rhythm from earliest childhood, & I was born in 1932. I particularly recall a heartbreaking rendering - must have been about 1937 - of 'The Little Red Caboose Behind the Train': the lines "The fast express came roaring at 90 miles an hour, The dew was frozen on the window pane, And as he was a-driving he said a silent prayer For the little red caboose behind the train" became imprinted [probably not entirely accurately] on my memory; & recur to me, in those odd, discrete moments we all have, to this day.
