• After frontman Eric Stefani left No Doubt in 1994, his co-vocalist sister Gwen, took over as the lead singer. Her brother had been the principal songwriter as well, so even though Gwen had never been particularly musical, she and the rest of the band needed to come up with some tunes.
  
  This slice of Ska/Pop was the first ever song Gwen Stefani ever wrote. The singer told The Daily Telegraph November 27, 2012 that the moment she started writing, she became a different person. "Before that, there was nothing I was good at, and, all of a sudden, here was something I felt really passionate about," she said. "I remember my dad listening to the first songs we recorded on his way into work and him saying, 'This is really good. You need to keep doing it.'"
• This fast-paced celebration of human diversity is apparently one of President Barack Obama's favourite songs. "How bizarre is that?," said Stefani to The Daily Telegraph. "The first song I wrote - which, when I read the lyrics today, seems so naive and young - and it ends up being one of the President's favorites."
