Never. The average radio listeners have no idea of who Roger Taylor or Brian May are. To them Queen is known by major hits like on Greatest Hits I, II and III. They might have one of those albums but hardly ever read credits. Sad but true. You could see on the venues Brian played on his last tour that it was much smaller. To reach a major audience they had to use the Queen name. That again led them to play mostly hits and not to include too many tracks that would have only be known to the "hardcore fans" as I would have hoped.
