Blue Moon over Bermuda

There was a blue moon while we were on the cruise . . .

From Wikipedia:
A blue moon is the appearance of the third full moon in a season that has four full moons, instead of the usual three. It is never visually blue. Because a blue moon occurs only every two or three years, the term blue moon is used colloquially to mean a rare event, as in the phrase "once in a blue moon".The second full moon in one calendar month is also sometimes called a blue moon. This usage results from a misinterpretation of the traditional definition of blue moon in the March 1946 issue of Sky and Telescope.
