It can be found here. I thoroughly enjoyed it. I think it could be titled: "A Short Guide To Deep Entertainment"... in other words, what I liked about it was that Nellson is not setting entertainment in opposition to theatre's other aspects (as many people do) but rather saying that entertainment is important and we can do that and do other things at the same time. Anne Bogart actually does a similar thing in... I think it's in And Then You Act... she talks about entertainment as one of the aspects of theatre, and says its an essential aspect and also talks about the other things that theatre can do.
