I, personally, have always wondered

what the hell this song was talking about

decided to share my favorite version

by The Three Degrees:

a more popular disco version is done by Donna Summer
(a gay/drag show classic)

well I googled the meaning of

"someone left the cake out in the rain"

and here is what I found

courtesy of Music Corner:

"... I wanted to share with everyone the meaning of the imagery behind the lyric about "someone left a cake out in the rain". There is a Disney movie called "So Dear To My Heart", which was kind of a period-piece of the early 1900's, and was about a little boy and his pet, a black lamb who always gets into trouble. In the opening musical montage for this film, animated scenes are shown of old-timey things from that era, and a picnic scene is shown, with no people around, because it has started to rain. The cake that is set out with the picnic food has begun to melt in the rain, and it is kind of sad when you think about it, how long it took somebody to make that cake and now there it goes, all ruined, and that must have been what Jimmy Webb was thinking of in his subconscious mind at least, when he wrote that famous line in his masterpiece song, MacArthur's Park. So thanks for letting me share that bit of trivia with all of you, rent the movie if you must see it to believe it yourselves."
