Folk'n'Jazz now does a three part summer tour in outdoor venues, but this one at La Vigérie is
very much associated with John because it was he who first had the
idea of a themed concert there, in 2014.  All proceeds go to
Médecins sans frontières, and of course thanks to Jeremy and Iga for the
superb venue, which even has a very attractive indoor alternative.  
Very important: 
Please bring a folding (or otherwise portable) chair.
