Can anyone become a leader? - Hal Haller

i am really itsnreeted in the piano course, to learn to play for my small church,however i have no idea if the course is suitable for me.? I think it would be helpful if there were a sample which i could try my hand at to know whether it suits me or not. The piano video just isnt enough for me to know whether i want to buy it or not. Can anyone tell me what the piano course is like????
