Well done & Good luck Andy - I've been on local Radio (BBC & Commercial) a few times, interviewed in the studio, down the phone and by the roadside. 1st time was a bit daunting but after that it was much easier, try to imagine you are just getting your views over in a pub discussion. Best one I ever did was in the studio about a pikey invasion of a local park, I took a sheet of notes and must say points with me. They recorded it and did a few repeat broadcasts.

Make sure you are well prepared to get the salient points over.
