Was reading a review of the U2 By U2 book in my local arts magazine. The reviewer made one comment about Pop and quoted the band on another about the same album:
The reviewer rather tongue in cheek made a reference that Pop was the most expensive demo album ever made
The band (presumably Bono), made the claim that given the themes found within the song, that the album should have perhaps been better named "Shouting at God".
Very interesing perspectives...
