Buddy Miles Express will be featured with Sly and the Family Stones tomorrow night at 7 in University Hall. This will be the first visit to the University for both groups. Other entertainment scheduled for the weekend includes a mixer tonight and an outdoor concert Sunday. At fraternity parties this weekend, the IFC has requested all doormen to be sure the party goers have either a student ID or a guest pass issued by the fraternity. These will be closely checked at all houses. Brothers may issue guest passes at the doors of their houses. First-year men will not be exempt from this ID check; so rushees should go with ID in hand. Most of the parties will begin at 10 Saturday night at the fraternities.
