Re Q3 I'm sure it's California.
Perry Como (I think it was him) used to sing a song that started 'What did Della wear, boy?' and then went through the rest of the States in the United States. Somebody forgot to pay her 'Texas' and there was definitely a line 'Why did Cali phone ya ?'
yup agree ladyalex- but i read into the question that they were asking 'why'did cali phone---and cali phoned to ask how are ya (hawaii)
a;so cali was mentioned in the question already
i may well be wrong tho(not for the first time)
