I've got Penman's Satie book. It's always a pleasure to read about the Beautiful Epoch. However, pointing out that Satie is one letter from satire adds nothing of any relevance.
I've just got to the bit where he tells the reader that "furniture" includes "urn" and "future". Yes you're right, well spotted, but why leave out "fun", "unit", etc and Satie used the word "ameublement" anyway. I fail to see why he includes such stuff.
