For the Record - Jan. 30, 2008

Pink Floyd: The Backtracking column in Tuesday’s Calendar section reported that Pink Floyd’s “The Dark Side of the Moon” and “The Wall” sold nearly 40 million albums collectively. The figure was based on a Recording Industry Assn. of America certification of 15 million albums shipped for “Dark Side” and 23 million for “The Wall.” But the RIAA gives the band double credit for “The Wall” because it is a double album. That means the individual number of copies of “The Wall” should be about 11.5 million, which in turn means the total sales figure is closer to 30 million.
