I love covers like this. Rarely do you find abstract works that are so effective at conveying what a single is about. Whisper to a Scream (Birds Fly) is a great song, and this single works on a lot of levels. It's not overtly commercial and so you can't claim that the band has "sold out" in any way.
On this version of the vinyl label, you can clearly see that there is a "European" version of the single. In 1984, U2 would release a longer version of Pride for the International market as well. Apparently, you had to take a razor blade to singles back in the day if you wanted to release them in America.
