"Pride", but for the simple reason everytime they play it live they murder it.
The tempo always drags and it sounds like hell live. It should be jettisoned from live shows forever unless they come up with a version that they can play with some authority.
"Bad" is okay but that song has always suffered to me because nothing will ever take the place of the Live Aid version--I've seen them do crappy versions and good versions, depending on the night, but never have they matched the scorcher that one was.
"Desire" became tiresome when they started doing the unplugged version, which merely highlighted how slight the song really is. Without those booming drums and Edge's chiming guitar, it sounds amateur.
