Another example: everyone knows the name of the lead singer of a band - rarely do they know who the rhythm guitarist, bassist, or drummer were.
I know Eddie Vedder is the lead singer of Pearl Jam, but I was never a huge fan. I like their music, but was exposed to it mostly through friends, who could almost certainly tell you the other important names in the band.
I think it's more probable that once a generation passes, more of the people who are even aware of the band are the fans who know more of the details.
