That's like, whoa, a huge deal. They dynamic of the band is different. It has to be."I've got two babies and their nanny, and an assistant, and my security, and a hairdresser. It's not as much of a party, but that's what I need in order to perform every night."The 'Don't Speak' hitmakers - also comprised of Tony Kanal, Adrian Young and Tom Dumont - are due to embark upon their 'Summer Reunion Tour' in Atlantic City, in the US, tomorrow (02.05.09). But Gwen, 39, says the group - who first formed 23 years ago - won't be hitting the road together, as this time round each member will have their own tour bus.She said in an interview with Spin magazine: "When you've still got the endorphins going from the show, it's so much fun to all be on the same bus, hanging out and drinking champagne. But there's no way that can happen anymore!"
