So, let me explain this. Garland is a wreath of flowers, leaves, and other similar materials. Gay means happy. So in phrasing "we bring back a garland gay" it means that "we bring back a wreath of flowers and leaves happily." Garland Gay isn't really a phrase you use in general, because "wreath of flowers and leaves happy" doesn't make any sense. Gay was describing the mood that the person saying the sentence was in, when the person brought back a wreath of flowers and leaves.
A Greek custom is to make a wreath of flowers to hang on your door for May Day.They make a wreath of flowers and hang it outside their door.
