Lay's best throw of 67.89 m was achieved in London on 7 July 1928 prior to the 1928 Olympics.[3] Officials thought he had broken the world record, but they had overlooked Eino Penttilä's record throw of 69.88 the previous year. Lay's throw remained the Commonwealth record for 26 years.[4]
Lay was a signwriter at Stratford, and could not afford the time off to go to the 1934 British Empire Games in London. At the 1950 Empire Games Lay took the oath on behalf of all competitors.[4]
