My father worked for 40 years with the firm that bought the patent for Ferguzade, which was called Lamb's lemonade, a Forfar firm dating back to the late 1890's. Mr Ferguson, the man who made his patent of the glucose based drink, was taken to court on the grounds he had sold the patent also to Lucozade. However the forfeiture was wavered by Lamb's, and so Lucozade also became available on the softdrink market. So Lamb's or Strathmore Springs, Forfar as it became known, continued to sell it on the market for soft drinks. Maybe this can help to understand the history of a very healthy drink, though I believe that Strathmore Springs was taken over by IRN BRU, and now the original name of Ferguzade is forgotten in history, alas!
