Judging on what was said in the 'acknowledgement of receipt' email, I'm under the impression that the material we sent in will be used as an audition of sorts, to see if the producers like the cut of our jib; not necessarily to be included in these advance shows (although they might include some).
Even though it's just a few test episodes, I still think they'd want the material they used in them to be quite recent/topical, which makes my material on the floods redundant for these shows, but hopefully they'll like the style and offer me the gig for the commission!
