"Did the choir even exist at this point?"

There's a very interesting interview with Dennis Bell, the conductor of the Gospel version of "I Still Haven't Found" from Rattle and Hum,  up on @U2 today. It includes a great deal of the backstory of how this version came to be, which -- I suppose we should not be surprised -- is a little different than the impression most people have of what happened. Hagiography has a way of smoothing out the rough edges and coming up with a better story.
