Spang new Allston Burr Lecture Hall made its debut as a theatre yesterday when a crowd of 500 watched Thomas Lehrer 5G and four assistants--enact. "The Physical Revue," a satire on the University in general, and science courses in particular.

Lehrer former Teaching Fellow, onetime section man in Math 1, and author of the "World Tree" poem--wrote the show last year, and presented it as the final lecture in Physics 11a.

Its success at that time induced him to present the show, with newly-written material and songs, again this year, for the second year in a row.

Although yesterday's performance had received only scant advance notice, every seat in the hall was filled long before the show began; even the aisles were occupied. Lehrer and his associates--Munro S. Edmonson. David Z. Robinson, Richard N. Schwab 3G, and Robert H. Walker 6G kept the assemblage laughing for a full hour.
