ALOHA!! Happy May Day Everyone!! Lyrics & Music: Leonard Hawk May Day is Lei Day in Hawaii Garlands of flowers everywhere All of the colors in the rainbow Maidens with blossoms in their hair Flowers that mean we should be happy Throwing aside a load of care Oh, May Day is Lei Day in Hawaii May Day is happy days out there According to Harry B. Soria, the celebration of May 1 as Lei Day was invented in 1927 by island artist and writer Donald Benson Blanding and Grace Tower Warren. Don Blanding is also credited with the invention of the custom of tossing your lei overboard when you sailed away from Honolulu. If the lei came back to shore (and most did) it supposedly meant you would return.
