Friday afternoon at 5 the Sandpipers will give a concert at the Cabell Hall end of the Lawn. Tickets for the concert, sponsored by the University Union and the PK and German Dance Societies, are on sale to students at Mincer's Pipe Shop and the main desk of Newcomb Hall. Mike Piano, Jim Brady, and Richard Shoff make up the group, which began singing together in the Mitchell Boys Choir, and later cut their first hit "Guantanamera," after changing their name from the Grads to the Sandpipers.
