Edited sentence: The main melody line of many songs of Andrew Lloyd Webber's "Phantom of the Opera", that you can mainly listen on "Overture" and in "The Phantom of the Opera" songs, is extremely similar to main theme of "Echoes" by Pink Floyd, taken from "Meddle" album.This pushed Pink Floyd's leader, Roger Waters, to regret for this questionable plagiarism, but refusing to sue Webber because "life is too short" for this sort of things (historically speaking, Waters generally has no luck in court lawsuits).Waters, anyway, in "It's a Miracle" song from his album "Amused to Death", had very strong words against Webber's supposed "theft"
