I tried to book Arnie as a pianist for Catholic church wedding since I do not like organs. Arnie was always pretty quick with responses and kept a professional manner whenever we exchanged emails. He had approved the songs I requested and even offered to learn a couple of untraditional processional songs that I wanted. I sent him the ceremony outline which he approved, however, about 2 weeks before my wedding, he had offered a colleague of his to work my wedding. I come to find out that Arnie does not know the layout of a Catholic ceremony and even told my cantor so. The replacement was wonderful on the piano and was even a former music director for a local church. I'm sure Arnie would have played beautifully, but I didn't appreciate him approving the program and saying he can do it when he didn't know what it was about. For a wedding mass, the musician is very important. He needs to know what songs to play, at what key, and when they're played.
