Palmer is among a tiny handful of prolific singer-songwriters who rarely misfire when writing for children.  This time around he may have once again written a best seller.  What a World We'd Have (If Christmas Lasted All Year Long)  is a heartwarming opener for everyone who cherishes peace on earth, good will to . . . etc.  He turns the standard holiday tune on its ear: you've never heard Jingle Bells  or Rudolph ... performed like this. Palmer takes another unpredictable turn with the self-penned The Merry Hula. Complete with Hawaiian guitars, it conjures up visions of a snow white luau.
