Plot: ""Tonight's story, 'Big Business', is about Reginald Mulliner, a young man of slender means and slighter intellect who before the dramatic change in his fortunes had only two assets in his life -the love of Amanda Biffen and the ability to sing Old Man River, a talent we discover him exercising in anticipation of the annual church concert in the village of Lower Smattering On The Whistle,Worcestershire.
