Electric Co- Sounds amazing live, and the chance to sing along with Edge's backing vox in the chorus 'Electric Coooooo' is just too good!
The Fly- Sounds as great as it does...when the drums kick in after the guitar intro...wow!
COBL- The intro....wow...goosebumps!
WOWY- Really powerful on this tour, and its nice to hear it with a bit of power back in the track.
Yahweh- Not a fan of the album version, much prefer this.
Bad- Havent heard it on this tour yet...
But from the boots, its sounding amazing, better than ever even!
RTSS- Just gorgeous, and its even more emotive when it closes and the declaration of human rights beginst to play.
Vertigo- Rocks. Enough said
LPOE- So, so much better than the album.
To narrow it down to one, i'd probably go for LPOE. Simply because of the vast improvement from record to live, it sounds great and Bono's drum work is...original...
