I came across this article from the Daily Independent dated 27th August 1937 relating to a gala night that was held by Oak Street Methodists Club at Sheffield's Heeley Baths the previous night.
From the brief description it seems as though the Club used a "steamer" as a substitute for the Titanic and some form of explosive device as a substitute for an iceberg. After the crash all that was left of the "steamer" was a "few blown-up tyres."
There may have been some point if the Rev E. Hardy had at least said prayers for those that lost their lives but in the "darkened baths" he merely read a brief narrative that was succeeded by a "searchlight thrown on the water". Strange times!
