[LAU] Advice on scripted assembling and mixing of a Radio Show

I have started a radio show called the Midnight Freedom Show. I plan on featuring one Free licensed song each night just after midnight. It is expected to play on Y98 in the Bahamas but I am also in discussions to get it to play on several college radio stations as well. (If you can help me get it on other stations as well, all help would be appreciated.) What I think I need to do is something like: [Station Name] this is Z bringing you the Midnight Freedom Show, tonight featuring [Song Name by Artist] etc. [song plays] That was [Song Name by Artist] here on [Station Name] etc. Show ends. Oh, and there is a bed playing under the DJ bits. So, the show should be "customized" for each station but I don't want a huge workload for myself and I don't want to push the work down to the stations unless they want it. So I am wondering if anyone has any ideas on how to script this up so as to assemble the bits automatically for each station. (I hope what I am asking is clear, if you need clarification, please question me until things clear up.) I think I am going to look into the possibilities of ecasound first. all the best, drew
