Taken from the Speedway Riders Index 1929-2022:
Bernie Lewis LAGROSSE
Born: 2 August 1939, Christchurch, New Zealand. Died: 30 June 2007.
Career record: (1965) Glasgow; (1968-70) Berwick.
NOTE: This rider originally rode under his real name of Bernie Lagrosse for Glasgow in 1965 but, when he returned in 1968, Trevor Redmond took some riders to Wales and said if anyone volunteered to be a Welshman for the night, there would be a bonus in it. Lagrosse agreed and Roy Williams was born!
