Playing For Weddings

I was peacefully minding my own business getting ready for church to start last Sunday when I felt a tap on my shoulder; I turned around and there was a guy named Joe Goodman who is getting married this Saturday to his high-school sweetheart; he said, "Um, I don't know if anyone has broached this subject with you or not....but my fiance and I were wondering if you would be willing to play for our wedding." I had heard that they were considering asking mom and I to play one song during the wedding, but it soon became apparent that they wanted me to play the piano and mom to play the flute for the entire ceremony; prelude, bridal march, dismissal, everything. In five days. I was a little shocked. I guess not very, though; there is nothing typical about this wedding. You see, Joe is 85 years old. He used to date Viola in high school, then they went their separate ways and had lives and families, until both of their spouses died awhile back and they conducted a telephone re-romance from two states and eventually fell in love again (or maybe they always were?) and now are getting married. It's the most adorable and adventurous thing!
Anyway, the critical part of this announcement is that tonight is the rehearsal. To say I'm panicked would be an understatement. I can play like a virtuoso (well, maybe not quite that good) as long as nobody is watching but as soon as I have an audience everything sounds like a poor version of Chopsticks.
Pray for me (and mom). Tonight and tomorrow.
Thanks!
