The first thing you need to know is that there’s a blue moon coming on August 31. Mental Floss posted an article about what they are and they’re more rare than you think due to weird farmer math.
As for the song, one of my favorites, it was written in 1934. I love the idea of finding a rare blue moon love under a blue moon. Blue moons are the third in a seasonal cycle and so always fall in Indian summer or early fall — and thus they make me think of hayrides for some reason. Probably the farmers.
It’s become a standard that’s been reinterpreted by dozens of singers — from Sinatra to Ian McCullough to Billie Holiday. There are quite a lot of takeoff songs on the concept as well. Big Star, Toby Keith and Stevie Wonder all have their own, original blue moon songs.
It is made most famous by Mel Torme. I do like this version by Cowboy Junkies. They give it a smokey feel.
