This week's installment of Cool Tunes for a Hot Planet is an eclectic mix of thematically related songs. Ukrainian Now, by Tom Paxton and John McCutcheon is an ensemble production lamenting the Russian invasion and exhorting us all to come together in support of the embattled Ukrainian people. Larry Lobert's Isn't This a Time is a call-to-arms folksong raising the alarm about the current-day rise in fascism. O the Ocean Rolls, by James Kahn, is a sea shanty looking at the personal struggles of a boat full of refugees. And The Right to Live in Peace, a group song inspired by a Victor Jara composition, and sung by the masses during the Chilean uprising of 2019, asserts the rights of all people to live lives of freedom and dignity.
