The first of a series of "pop-nights" will be held in the Living Room of the Union tomorrow evening from 9 to 11 o'clock, at which the University orchestra will play all the songs accepted by the football song committee this fall. Printed copies of the words of these songs will be distributed. Small tables will be placed in the Living Room, and during the evening light refreshments, such as may be obtained at the lunch counter, will be served at regular prices.
