Tim Buckley: Dolphins, 1974

This song was written by Fred Neil in 1966.  Neil spent much of his life in dolphin preservation, but there is another layer in the lyrics about war, which would have been Vietnam. 

The early 1970s were an agonized time, a war had gone on too long for unsupportable reasons, the environmental movement realised just how quickly species were being lost and saw climate change rushing towards us like a dust storm. And poets picked up guitars.
