If you don't watch CSI (like we don't) if you're younger, you wouldn't have any idea who they were.
Not if you know anything about music. My 15 1/2 year old DD and her friends watching with us all knew "who" the Who were and they don't watch CSI. They also know the Beatles, Journey, Stevie Wonder, Foreigner, Boston, Allman Brothers, Doobie Brothers and on and on... DH and I get the biggest kick when she comes to us and plays a song she's downloaded and asks "have you ever heard this song?" and then we show her we still have the vinyl album.
