Frank Sinatra
"April Showers"

Though April showers may come your way
They bring the flowers that bloom in May
So if it's raining, have no regrets
Because it isn't raining rain, you know
It's raining violets

And when you see clouds upon the hills
You soon will see crowds of daffodils
So keep on looking for a bluebird and listening for his songs
Whenever April showers come along.
