There was a good documentary last year on the history of West Indies players joining the Lancashire League. The footage showing packed crowds and legends like Wes Hall, and later Viv Richards in his peak coming to the club he used to be play for as a young aspiring professional via a chopper from the other side of the country was amazing. It was these amateur leagues that provided young foreign talents the chance to impress county scouts. Those leagues in those days was more professional in terms of ground-keeping but also a higher standard since before central contracts were a thing you'd have ex England players playing.
