[Andrea]

The best songs are listed already so I would like to add:

-Faery Folk and Nightingale from Frankenstein
-You Do Scribble (Abbey Road Version)
-Louisiana
-Boy, Boy, Boy
-Good Morning Cockerel
* -Born Slippy Jam
* -Oich Oich
(* is it pre- or post-Emerson?)

I also like Downpipe and Beebop Hurry but I don't know if they are reckoned as U/W songs
