You would probably go through each row in the spreadsheet and highlight the compact discs from Johnny Rotten's bands." FYI: "Public Image Limited's Compact Disc is an example of such an album. The cassette version of the album is called Cassette." "Blessed are the sleepy ones: for they shall soon doze off.
