A friend of mine, a concert organist from Latvia, used to play French Romantic repertoire on one-manual and pedal organs in a few Somerset village churches. Lots of quick registration changed, and sometimes a bit of judicious re-arrangement, and it worked. I heard her play the Franck Chorale No 3, Widor Toccata and Vierne Carillon de Westminster along with major Bach works in Luccombe church on Exmoor and in Sampford Brett on the Quantocks. Some of the audience were amazed when they saw what little resources she was using to so great effect.
