Career
He was popular at conventions during the time he worked as a travelling businessman and owner of John Clouston Ltd. of St. John's, Newfoundland. He retired in 1975 and became a best-selling author of comedy books. His other albums included Spinn'Yarns and Come 'er till I tell You.
Alwyn was the son of John Clouston, grandson of Thomas Clouston (both of St John's), and the great-grandson of John Clouston, a stonemason from Kirkwall, Orkney (early 19th century). He was almost certainly related (at least distantly) to Brian Clouston, Sir Edward Clouston, 1st Baronet, Storer Clouston and William Alexander Clouston, as the surname Clouston is (according to Storer Clouston in his book Family of Clouston) exclusive to descendants of Haakon Harvardson Klo, from whom the name derives. However this is not supported by official records.
All that can be correctly stated is that he had the same surname as these Cloustons.
