"What Have They Done to the Rain" is a song by Malvina Reynolds. Composed in 1962 and first entitled "Rain Song", it was written as part of a campaign to stop nuclear testing in the atmosphere, which was producing fall-out.
The song was recorded by The Searchers, The Seekers, Marianne Faithfull, Joan Baez and Melanie.
I learned it from Joan Baez.
