According to 'The Lutheran' website, "a request was made to author Colin Thiele to write a short story commemorating the Lutheran Sunday School picnic. His handwritten manuscript 'The Picnic', donated to the school, was recently deposited at Lutheran Archives. Colin's story formed the basis of a picnic held in Tanunda in 1986 as part of South Australia's 150th Jubilee celebrations. Many schools came together, donned period costumes, and relived the old-style picnic, so vividly portrayed by Colin."
