Rock and roll was always about rebellion against the stale status quo. It often cried for liberty, and the rights of the individuals rather than the “establishment”. Dee Sneider came out of the hearing as the winner.
Hearings, even outside the grilling season, are done in a similar fashion. When a committee invites a guest for an “exchange of views”, the way it is handled in the committee is by and large the same. MEPs are lectured by the Committee Chair how to use their five-minute slot and how to ask a question.
