Rowling has yet to get Potted, reportedly, but it's not that she hasn't tried.

"The story goes, funnily enough, that at a show a few years ago in Edinborough, someone came along to try to get a seat at the last minute. The box office girl told the person, 'I'm sorry but this show is sold out.'"

After the show, the mortified cast and crew realized that the woman who asked for that seat was, indeed, Rowling herself.

"The girl, actually, was distraught; she was in floods of tears about it," Percy says with sublime forgiveness.

Since then, Potted Potter's people have borrowed a page from former Oilers coach Jerry Glanville's playbook. In the late '80s, Glanville thoughtfully and religiously reserved one seat for Elvis Presley in the always sold-out Astrodome, in the event The King ever wanted to watch a Houston NFL team win a game.

"Now we always save one seat back, for every show, wherever we play in the world," Percy a-day-late-and-dollar-shortly says.

They best save two seats at the Wortham, just in case. And expect Elvis to bring his own refreshments.
