The above gentleman, John Good, is a proponent of Welsh music, language and culture. He builds his own historic Welsh instruments, and plays them all well, including a harp. Some of the hymn tunes were familiar. The format was to sing a couple of verses in English and then listen to a couple in Welsh. The pastor of the church did the scripture readings and also told some Celtic Christmas legends.
The UCC is a good, liberal mainline church which doesn't require you to check your brain at the door, as evidenced by the plaques on the wall in the narthex, one of which read "Evolution happens!"
