Hey Broadway theatergoers, are you ready for some toe-tapping alienation, set to a score of lyrically bitter classic rock? Then brace yourself for the stage musical version of ''Pink Floyd The Wall.'' Roger Waters, the former Floyd composer and bassist who wrote all the songs on the landmark 1979 double-disc, will arrange and orchestrate the score and write the book as well. Producing will be former Sony Music chief Tommy Mottola and Miramax co-chairman Harvey Weinstein, who jointly purchased the stage rights from Waters some time ago.
''The Wall,'' which is the third best-selling album of all time in the U.S. (it's sold 23 million copies) and spawned such hits as ''Another Brick in the Wall'' and ''Comfortably Numb,'' has been adapted before, into a 1982 movie (with a screenplay by Waters) and as a lavish touring concert production by Pink Floyd in the early 1980s, a stage show that Waters recreated in 1990 for a Berlin concert to mark the fall of the Berlin Wall. The rock opera tells the story of Pink, a disillusioned, paranoid, emotionally stunted rock star who, like Waters himself, lost his father in World War II. But the musical, which Weinstein tells the New York Post should hit Broadway in 12 to 18 months, won't be quite so bleak. Said Waters in a statement: ''Now I can write in some laughs, notable by their absence in the movie.''
