(Better late than never.) Here's Rufus Wainwright's California, where he pleads, "my new Grandma Bea Arthur, come on over." I like to believe he wrote this, because Bea was some form of electric comfort via his television set during lonely times away from NYC.
He loves to tell the story of meeting Bea and spilling out this long, wordy tale about his including her in this song. The reason being that he and his Grandma really bonded while watching Golden Girls, and Bea, of course was their favorite on the show. Ever the sass-mouth, Bea just looks at him dryly, and retorts, "I'm not your fucking grandmother!" and walks past him!
