Malcom...I'm not surprised (sign me not a fan of PG).

Bob...Yes I have noticed that, and also that lots of mathmeticians are musicians, and vice versa. Many years ago I worked for a very high powered software company with lots of genius level mathmetician/programmers...and there was an inordinate number of classical (and other) musicians among them. Perhaps the same mental phenomenon accounts for all these attributes?

Kat...glad you enjoyed them too...

Still smiling
