Thank you, Lazlo, for reminding me of Jethro Tull.
I remember the moment, as teenager (I'm 59 now), that I realized 99% of musicians didn't mean what they sang. Silly me, I had thought that they were trying to communicate what they really felt. It crushed me, it dissolved my innocence. For most people, the 60's were a collection of trends and follies, not serious at all. They didn't mean it. How cool to be cool.
Now we really are Thick As A Brick.
