www.holytrinitytoronto.org/wp/2010/11/the-christmas-story-3/ There are two different casts and several musicians to cover all the performances. There was a dress rehearsal for each cast, one on Monday and one yesterday, and they went pretty well - it will be a good show. I sang both the dress rehearsals, and will be singing for the performances on December 4th & 12th. The two organists and some of the singers have been doing this for several decades. I'm one of the newest ones, this is only my 4th time. The first time I got called at the last minute to sub for a soprano who was ill - I was so nervous, but I must have done OK, because I got called again :-)
