Yep, Catfish was the same. Whoever was on the Chevron finished with about 3 songs to go, and the sound suddenly turned good, it felt like that it was interfering even if you couldn't explicitly hear it the whole time.
We went into the front pit for Liam Gallagher out of necessity more than anything else, and while the songs drowned it outwe could still hear it between tracks. They're going to have to sort it out somehow
