I'll echo A Sort Of Homecoming, One, and Stay. I'm almost inclined to say the same for The Fly and Until The End Of The World, since the production on Achtung Baby is so perfect, but some Zoo TV performances are exceptional. The Paris and Dublin shows are among my personal favorites.
Most of them.
I partially agree, knowing U2's poor record of committing quality productions to record. It's crazy to think that a band with as much draw as U2 has been so dreadfully inconsistent on that front, historically.
