Quite frankly, I can't think of any musical/semi-musical project that can score higher than R&G on insanity meter (although Rudolf Eber prefer to use term "psychotraining" to describe his work). On R&G studio recordings you can hear mr. Eber laughing (his trademark), shaving, falling, walking his dog (apparently), being somewhat distressed and doing other things which can't really be described with words.
