There was a time when rock&roll fans would have laughed at the thought of canceling a concert for political reasons. There was a minor uproar when the Fab Four upset people when they said they were more popular than Jesus and even a drug bust didn't bother anyone. As a matter of fact if you eliminate members of the R&R hall 'o fame for drug abuse it would be one big empty hall. The words hypocrisy and pandering come to mind. You could add chickenshit.
