According to "British Artists Today" she has lived in Geneva for 5 decades and since 2012 has rarely left Geneva! Is Jubilee Street in Geneva?
Petula Sally Olwen Clark, CBE (born 15 November 1932) is a British singer, actress, and composer. She was for a short time relocated to Warren Camp the Governments WW 2 Evacuee Centre for Children under 16yrs with 700 other kids. Of course there is another Petula but her surname ended with an e! Some Guy on here must live in Geneva?
I’m getting a bit of an inkling that you rather like Petula Clark.
