Have you read Wadler's papers? 

http://homepages.inf.ed.ac.uk/wadler/topics/monads.html

In particular one of "The essence of functional programming" or "Monads
for Functional Programming"?  If not, I think you'll find them better in
every way* than any "tutorial" despite being written 15 years ago.

* And I do mean -every- way; they are also more entertaining and easier
to read.
