well on the topic, i'll post my theroy.
The reason their's not much UYI songs is... because their not touring that album. Usualy 5 Chinese Democacy songs are played (Blues, Better, IRS, CD, and Maddy). So in reality their setlist does consist of the more *popular* UYI songs (NR, YCBM, LALD, KOHD, Dont Cry(solo)). Plus the added keyboard and guitar solo and the CD songs mentioned. That's 7 UYI song's that would be played if they were touring that album. Also with *option* songs like UTLH, Rocket Queen, DOWN ON THE FUCKING FARM... you know song's that are usualy on the setlist like once a week. So if they had UYI Options like they do (perfect crime) we come up with around a possibility of having about 10 UYI songs added. Because though, their no longer touring UYI their not going to play it's depth and make room for CD tracks.
