Thread: "Send in the Clowns" mentioned in what book?

This should be an easy question for you guys, but I can't remember what book references the song "send in the clowns" mutiple times. I know it is a popular book that mentions it, i just can't remember which. Thanks

I would know this of course... as I'm a huge fan.

That would be Fierce Invalids Home From Hot Climates by the one and only Tom Robbins.
