Once again the fine folk group known as Peter, Paul and Mary will grace the portable stage of University Hall. Sponsored by the University Union and the Virginia Student Aid Foundation, the trio from "I Dig Rock And Roll Music" fame will appear February 8, the first weekend of the second semester, at 7 in the evening. Tickets will cost $3 before the concert and $4 at the door. Tickets for the performance, which last year saw a capacity audience, will be available at Newcomb Hall, and Mincer's Pipe Shop.
