I was listening to the One Tree Hill iTunes Point Depot performance earlier today, and it got me thinking that while the studio version is one of my favourite U2 songs, it just doesn't seem to cut it live. Are there any songs which you think don't live up to expectations when performed live, and also, are there songs which have exceeded your expectations when performed live? One such example in my mind, specific to this tour, is 'Yahweh'. I had not cared for this song until I saw them live, when I found it to be absolutely stunning (especially with the addition of the strings).
I should also add that despite the widespread desire for it, I don't think Acrobat would come off so great if it were to be performed live.
