Do not accept any late Music 10 attendance cards

Do not accept any late Music 10 attendance cards. Three Music 10 students arrived late for the 4/11 concert, were told to wait in the lobby for the first break, upon which they would be admitted. They moved outdoors to talk, with attendance card in hand, and then suddenly disappeared without attending the concert. If they have any issues with this, tell them to see Mr. Klice when he is working in the Music Lab.
