I am envious, FinnViking, that people are actually listening to your music in church.
Where I play, the prelude is treated as muzak and the din of the gathering is such that I, at times, cannot even hear what I am playing. I've protested many times to the pastor and worship committee and nothing ever gets done. The prelude is as much a part of the service as the lessons, imho.
One year, when April Fools Day occurred on a Sunday, I played (and I kid you not) a very slow reverent version of I'm a Yankee Doodle Dandee ... for the prelude ... and only two people caught on, both members in the choir. Not another soul in the congregation caught on to the prank, including the pastor.
When visiting Denmark in 2010, we attended a Lutheran service where Frederik Magle was playing as the substitute organist. The service began with the announcements, then the pastor sat down and the prelude began with a quiet church. Same was true at the end of the service, after the final benediction, the pastor sat down and the postlude was played, again in a concert like environment.
