I do - well did. I haven't played in a church regularly since I moved here 10 years ago. I thoroughly enjoyed it. I am a classically trained pianist, so had to adapt my style for the organ and then cheat on some of the methods, as my hands are very small. But there is nothing like opening all the pipes up and giving it laldy! I also sing along with the hymns while I play, which came as a shock in each church initially - and then I used to sing the descants to carols while still playing the tune to lead the congregation. Don't ask me how I did it, because I have no idea. Both hands playing something different, my left foot on the pedals (I learned on a half pedal board, so only used the one foot) and then my voice doing something else again. Extreme multi-tasking!
