I don't know that anyone is "in the know" on this event. We're still asking around for more information, and even our CM friends don't have anything more to add to what little information Disney has put on the website. I've heard a rumor about the swing band at IASW (thankfully it's one of the regular bands at the Royal Swing Ball and a very popular one with the dancers), but nothing about the 60's band at the train station.
