I love these pics of Steve Jones, they make me laugh. But why is he dressed as a builder? Well, tonight 4Music launches as a spangly new channel, featuring music shows, exclusives, festival coverage (V is featured this weekend) and artist interviews alongside the usual fare of vids and countdowns. Tonight lovely Steve and Davina McCall will kick off proceedings with their 20 Big Ones which sees Steve dressing up as a "camp builder" – a male version of those under-dressed women in Benny Benassi’s "Satisfaction" vid. Nice. Here's what Steve and Davina had to say about the launch:

• Can you describe your opening show on 4Music?
  Steve: "Think of Steve and Davina’s Big Ones as two hours of music labour where at the end where we give birth to Kylie Minogue (in concert – the world exclusive of KYLIEX2008 at 9pm). But without the pain."

• What’s it like working with each other again (after last year's Big Brother special)?
  Steve: "For me and Davina to present the first show... it’s a true honour. I love working with Davina and really enjoy being on screen with her."
  Davina: "I love Steve! He make it so easy and we’ve just got a very good rapport, the more I work with him the better it gets. I do hope I get to work with him again."

For more from Steve and Davina, details of tonight's schedule, more photos and the TV spot featuring McFly, Sugababes, Kelly Rowland, Duffy, Miquita Oliver, Alex Zane, Alphabeat, Alexa Chung, The Saturdays and others just read more

• What is it about 4Music that you’re looking forward to?
  Davina: "The live coverage of gigs. I don't get to many gigs with three kids! I really miss the live aspect."
• How do you feel to be hosting the first ever show on the channel?
  Steve: "I couldn’t be more honoured to present the first ever show on 4Music. The future is very bright for 4Music, so why shouldn’t it have its own channel?"
  Davina: "Its brilliant ...a real honour. I started my career on a music television channel so it felt rather good and to be the first people on the channel is pretty exciting. I am totally passionate about music and couldn't live without it, so thank you 4Music!"
