West Park RFC was formally established in August 1947 at a meeting held in the Black Bull Hotel, though occasional matches had been played the previous season under the title "Catholic Grammar School Old Boys."

The team regularly had to collect debris that had erupted from the ground, and on one occasion a match was interrupted whilst a full-sized perambulator was excavated.

Another match venue was the Alder Hey Road field: "Remarkable for the depth of its mud, making Passchendaele and Ypres look like the Gobi desert in high summer."

Club members spent the season – on what is now Carmel College playing fields – digging drains with the help of an elderly milk horse, called Dolly, borrowed from Friths' Farm.
