It's April, and outside the window it's raining today. This unseasonal 1937 Harry Warren melody just seemed appropriate!!
It shows off the lush, dreamy side of the organ. For a subtle change, I have based the tenor melody registration around the sub tierce tibia rather than the more usual quint which adds a rather different character to the sound.
The "raindrops" are inspired by Quentin McLean's famous arrangement of "Rain on the roof".
