Caroline Kraabel, John Edwards, Oren Marshall, Cath Roberts, Sue Lynch, Shabaka Hutchings, Beibei Wang and a group of London's finest acoustic musicians from the world of jazz and improvisation are planning to travel for two days to La Jungle in Calais and Grand Synthe in Dunkirk to perform for and with the people living there, and bring them donations of musical instruments. Our contacts in the groups that support the refugees tell us that this would be a useful and welcome intervention.
