Yep, I read that one years ago, but have pretty much forgotten it ― except that it cast Woodstock in a very positive light, as I recall. For example, Woodstock may be boorish in I.iii, but you can be pretty sure most theatre-goers agreed with him. I got the sense he was a very popular figure in Tudor days. (An acceptable Puritan?)
IV.i: the disguised masquers is the same trick used in a number of plays, most especially The Malcontent and its parodic/comic successor, The Revenger's Tragedy. I forget when Woodstock was written.
V.i. Many things come in pairs in The Revenger's Tragedy also. And, it is refreshing to read something in which a Cheney is a good guy.
