Interesting to know that J.S.Bach spent most of his life as a church organist and a choir director!

Colin, thank you for nice words, comparing, but I'd have to say, J.S.Bach is a genius, I'm just a videographer, the level of related invention is incomparable!
J.S.Bach's figure will stay forever, that's the nature of the music that he left, for all humankind,
we, videographers leave an event record with possible personal touch, for couples and their relatives!
