CG-ing today, and it's Christie, "San Bernardino", their follow-up to "Yellow River". I've never heard this -- nothing like Brits singing about California even tho' they've obviously never been there (First Class's hilarious reference to San Jose in "Beach Baby" is another example).
Bwaha! I know exactly which other songs you're thinking of:
Kim Wilde's odd interest in "east California" in "Kids in America"
Diesel's entire fucking journey in "Sausalito Summernights"
Obviously Gordon Lightfoot has been to California, but I always get a hoot when I hear his version of "Me and Bobby McGee" and he sings 'somewhere near suh-lie-ness.'
