Thanks all - some good memory joggers here
(at my age & stage I'm hoping to re-learn, rather than start from scratch)
Whales seem to form a sub-section here.....
my favourite remains "The Whale" by Malvina Reynolds, whose prodigious output also provides "God Bless the Grass" & others.
And there's Paul Seibel's "Prayer Song",
Fred Hellerman & Fran Minkoff's "Healing River",
Pete Seeger's "Well May the World Go"......
