According to the Guardian, David Bowie has been the only artist to officially declare that they will not cover a Peter Gabriel song for the latter's follow-up to the terrible Scratch My Back.
Why not, you ask?
Your answer:
Kudos to Bowie for being the bigger man, and not seeking revenge for this monstrosity on one of Gabriel's tunes.
Of the artists whose work Gabriel butchered, only the Magnetic Fields and Paul Simon have gotten back to him thus far. The Arcade Fire were supposedly covering "Games Without Frontiers," but it looks like they've dropped out. Thom Yorke has been on and off about the entire thing, and many of the other artists have yet to even comment on the matter.
