Great plan,

Just a little word of warning if you are also researching listings yourself, a friend of mine had a little trouble with a listings compiler when he tried to use information from their site for a radio programme including live gig listings. The person concerned was annoyed that he did all the research then someone else just swanned in and used it for their own project without any recompense. Personally, I think if you've published information it is there for other people to use (creditation included). Just watch out for upsetting people if you don't need to, try and ask for permission first.
