"I still work on the old Newtonian physics. My son is doing A level physics and he can do quarks - but we can both pick up a pint of beer ok."

Not entirely fair I don't think.

Josepp is getting ragged for saying that he knew a guy who was misinformed by a charlatan posing as a music teacher.

The "teacher" accepted money in exchange for false information, not knowing whether that information was true or not.

It would be like me accepting money from someone for telling them that there is definitely only one law of motion.


PS - my reading, like yours, is painfully slow - but knowing how opened up many doors.

You wouldn't say to a dyslexic person that they shouldn't bother learning to read books - and the same principle applies in music.
