KENNEDY TRIP: IRISH ROAR WELCOME AFTER GERMAN VISIT: As President Kennedy continues his working visit to Europe he visits an outpost of free men and democracy - West Berlin. The East Germans blocked off the Brandenburg Gate with Red banners to block the President's view as he visits The Wall of Hate. Later; before City Hall; 150;000 jam the Square to hear the President say that all free men; wherever they are; are citizens of Berlin. From the tumult and frenzy of Berlin to the quiet pool of Ireland; his next stop. No matter that he is three generations removed from the Old Sod the Irish say a native son has returned.
