This is about Bud Flanagan, from Wikipedia. Flanagan was most famous for being one of Flanagan and Allen, and for ‘Underneath the Arches’ and the ‘Dad’s Army’ theme.
“Flanagan was born in Whitechapel, in the East End of London. His parents, Wolf Weintrop (1856–1932) and Yetta (Kitty) Weintrop (1856–1935) were Polish Jews who were married in the city of Radom, Poland, and fled to Łódź on their wedding day to avoid a pogrom. Wolf and Yetta Weintrop intended to escape to the “New World” from Eastern Europe – they paid for a ticket to New York, but a dishonest ticket agent gave them a ticket to London.”
The bit I like is this:
“In the Army, he worked as a driver and entertained the troops with his singing and impersonations. Here he met the anti-Semitic Sergeant-Major Flanagan, on whom Reuben later had his revenge when he adopted the name “Flanagan” as his stage name.”
