My Last Sondheim Post (for at least a week or so)

This blog has been a bit Sondheim-heavy for the last couple of weeks, but I am a fan, and so many others are as well, aren't they?
Not the least of whom is the impressive Michael Ball, who worked with Mr. Sondheim on Passion - one of his lesser-known masterpieces.
Ball wrote a blog/essay recently for The Guardian about that experience and about his impressions of the musical master.
I thought fans of Sondheim (and Ball) might enjoy reading it.
