Les Thornton started out as Les Thornton and worked as Pierlot along side his real name. The Pierlot idea must have been from a promoter. I can give examples as early as 1958 where he worked as both.
The Globe bill see's him as Pierlot .
So even though the Pierlot idea was there you can still find him as Thornton in 1960.
After Les went over to Joint , he worked mainly as Pierlot , but still was billed as Les Thornton some of the time.
I knew him better as Henri Pierlot. When did he change to Les Thornton?
