There's a reason why the Spice Girls declared Toronto "Spice City" and honoured it accordingly with four separate shows. It's because we're bat-shit crazy about Posh, Scary, Ginger, Sporty and the other one. The Girls' show on Sunday night at the Air Canada Centre was near-Roman in its level of spectacle and over-the-top excess, complete with costume changes, catwalks and lurid moments. And everyone loved it.
