Well there's always Scottish Rain by the Silencers, Jerry Garcia and David Grisman singing Dreadful Wind and Rain or Julie Fowlis with Wind and Rain.
If I may chuck in a poem, there is always During Wind and Rain by Thomas Hardy.
All good depressing stuff Brian....lol
Tina Turner's -I Can't Stand the Rain. Just saw that Brian already posted this one. So... honestly the first one that came to my mind was - It's raining it's pouring the old man is snoring , he fell out of bed and bumped his head and couldn't get up in the morning.
Ann Peebles - I Can't Stand the Rain
Prince - Purple Rain
Rihanna - Umbrella
Brook Benton - Rainy Night In Georgia
Then all those others on Facebook...
