Guest host Dennis O’Hare presents two unorthodox love stories at a time when we could all use a little love.   British writer Jane Gardam twists Hans Christian Andersen’s tale in a saucy reboot of “The Little Mermaid.”  Her version, “The Pangs of Love,” is read by Jane Kaczmarek.  And Sharon Gless performs “Hat Trick,” by Edith Pearlman, in which four young girls choose husbands by chance.
