BBC News By Mark Savage It came out of nowhere. It changed the course of pop music. It was Wannabe - the scrappily brilliant debut single by The Spice Girls. The record label had been worried. Wannabe was too weird, too anarchic. They hated the video. BBC Radio 1 was refusing to play it. Breakfast show DJ Chris Evans told the band to go back to kids' TV. But the girls knew better. "It's not negotiable as far as we're concerned," they insisted. "Wannabe is our first single." And "if they decided they wanted to do something, then that's what was going to happen," Wannabe's co-writer Richard "Biff" Stannard told the BBC.
