plagiarism

'In interviews promoting Amused to Death, Waters asserted that Andrew Lloyd Webber had plagiarized themes from "Echoes" for sections of the musical The Phantom of the Opera; nevertheless, he decided not to file a lawsuit regarding the matter.

Yeah, the beginning of that bloody Phantom song is from Echoes. *DAAAA-da-da-da-da-da* [sic]. I couldn't believe it when I heard it. It's the same time signature - it's 12/8 - and it's the same structure and it's the same notes and it's the same everything. Bastard. It probably is actionable. It really is! But I think that life's too long to bother with suing Andrew fucking Lloyd Webber.[6]

Waters did, however, respond by adding a reference to Webber in the song "It's a Miracle" on the Amused to Death album:

We cower in our shelters, with our hands over our ears
Lloyd Webber's awful stuff runs for years and years and years
An earthquake hits the theatre, but the operetta lingers
Then the piano lid comes down and breaks his fucking fingers
It's a miracle'
