From This Might Be A Wiki
Hope this is OK. It will need formatting somewhat, but I am doing this on a phone in the cafe-ish area of the Hall building, so cannot do that right now. The setlist I've done is as performed, written down while being performed, so may not be the same as that given out at the end of the show to the people in the stalls.
The photos took of the kids show are at http://www.flickr.com/photos/oharab/4771841217/in/set-72157624319677597/
You're free to add them if you like.
from a little digging id say the balloons were probably the Festo AirPenguin and AirJelly
