Seriously. "Falling Down" is awesome, and adding guys from H2O and Youth of Today is just a bonus and killer way to close a record.
"The Unheard Voice" (cut from the retail version for some reason) is a great addition to the album, you should grab if it you don't have it (it belongs after "Dive Right In"). "The Heart of Polka" is a bonus track (recorded in early 2004), and another good one to stick on the album.
I'm really excited to see what they do with "re-imagining" this album.
