The Poets' Theatre proves once and for all that Bridey Murphy is an intellectual in its first production of the year. The Lady and Her Sources, which concerns the biography of a very alive pretty young girl who has been dead for 100 years, finally asserts the Poets' penchant for clear thinking. The Bald Soprano, a farce, also got hilarious reviews. Today, at 3 p.m. and 8:30 p.m.

Bells Are Ringing, ding dong, all over town. With Judy Holliday and J. J. Shubert in a real money-winner. At, curiously enough, the Shubert. At 2:15 and 8:30 p.m.

Long Day's Journey into Night is probably one of the greatest plays ever to play Boston. With Florence Eldridge and Frederic March pounding tragedy for four hours into every member of the audience, it is truly one of O'Neill's very best. Last performance at the Wilbur, 7:30 p.m.

Rin Tin Tin is featured "in person" with a "complete" TV cast at the Rodeo plus the Collins Kids, all of which have ousted the Bruins from the Garden. At 10 a.m., 2:30 and 8:30 p.m.
