i read the SNL book: Live from New York so here's my thoughts on this intriguing beef:

1. Lorne hates those 'Eddie years' because to him it was a one man show not an ensemble effort for laughs, which is why HE BOUGHT THE RIGHTS AND NEVER PUTS THOSE YEARS IN SYNDICATION EVER.
2. friends and early collaborators Keenan & Robert Townsend were castoff the show, always thought Garret Morris sketches were demeaning = EDDIE THINKS SNL DON'T FUCK WITH BLACK COMICS FOR REAL
3. till this day Lorne still thinks john belushi is the funniest to ever come out of SNL
4. spade's 'falling star' barb was the tip of the iceberg

*he also didn't wanna play Cosby on the 'celebrity jeopardy' sketch because, well....
