PETER BLAIR NOONE (better known to you as HERMAN) has become quite a loner as of late. His real friends outside the group are few. And those he has, he chooses with the utmost care. He admitted to us that he rather enjoys his own company. "I like being on my own," he grins. "I even like talking to myself because I know what I'm talking about! Most afternoons, I just wander around, spend hours walking all over the place." If you'll pardon the pun, sounds like Herman is becoming a bit of a hermit! . . .
