One of the most important tracks on the deluxe edition is Fall At Your Feet early version.. well it and Left Hand... though Left Hand is important across various albums...
The Finn demos are great as ever, Fields Are Full Of Your Kind is a great addition.
The unheard song demos are very interesting - they consistently show how the writing process works - stick with them as they will suddenly morph into something you know..
and how could I forget Be My Guest - why was this never given a full album spot?
