A Benefit concert will be presented at Memorial Hall (Sanders Theatre) in Harvard Square on Saturday night, January 16th. Money collected will be used to pay legal fees facing the eleven students under indictment by the State Department for defying the travel ban which has been placed on the visiting of certain countries. The students involved and their supporters demand the freedom to be able to travel anywhere they desire as long as they are allowed to enter by that country. Judy Collins, whose last Boston concert was sold out, Eric Andersen, and Dick and Mimi Farina will be the artists who donate their talent to the cause.
