Very interesting post from Stanley Shapiro, assuming the post is in fact from him, and given the details it appears highly likely that it is.
I've never heard the story that Brian thinks Shapiro and Jakobson stole his piano, and I would have assumed, perhaps incorrectly, that someone who was a good friend of Dennis' would not have had a drug free past.
Checking the BMI and ASCAP Repertoires, I am rather baffled, as I have no expertise in this area, as to how to interpret the numbers as far as percentage of writer's credits and publishing are concerned, as they seem to be in conflict.
