I was browsing cracked.com (I love that site) and found this hilarious cartoon describing the timeline of rock in various ways. You can check it out here.
I love that....that's great. Maybe there should've been a caption for the "Morons", "Should've been on drugs," they might have been better.
I think it's funny because it's true. Rock started out as a business only which is why the drugs were kept secret. For appearances and all. Now it's come full circle and it's treated as more of a business again. For better or worse.
