			From: Sadie Bowman <calculusthemusical@gmail.com>
			To: calculusthemusical@gmail.com
			Subject: "Calculus: The Musical!"

			Greetings!

			Please read and feel free to forward/distribute amongst your colleagues
			and students.

			I am contacting you from Matheatre, a performance duo originating in
			Minneapolis, Minnesota. We are excited to announce that our newest
			touring show, "Calculus: The Musical!" is scheduled to perform a limited
			engagement in Toronto September 28-30!

			"Calculus: The Musical" is a comic "review" of the concepts and history
			of calculus. Using musical parodies that span genres from light opera to
			hip-hop, the quest for the instantaneous rate of change and the area
			under the curve comes to life--through song! Written by a licensed math
			teacher, "Calculus: The Musical!" puts the "edge" back in "education!"

			"Calculus: The Musical!"
			Thursday, September 28, 7pm
			Friday, September 29, 7pm
			Saturday, September 30, 8:30pm
			Unit 102 Theatre
			46 Noble Street
			(near the intersection of Dufferin and Queen)
			Tickets: $10.00

			Visit our website for more details:

			Thank you and we hope to see you there!
