I saw a commercial for the WGN morning news a short while ago and they mentioned something about The Redwalls. I wasn't really paying attention, but I'm assuming they're going to be on the show tomorrow morning. There's no info on the WGN site yet, but I'll keep checking. The morning news is from 5-9am but it's likely that they'll be on between 7-9am.
ETA You can watch their performance here and see some photos of them here.
Let's hope someone fixes the captions/labeling on the photos. :\
