Dear Natalie,
I just wanted to write a quick thank you for the wonderful music your ensemble played before and during our ceremony. I know my wife will be writing a more formal note, but I wanted to personally let you know that I really appreciated the music.
I was especially delighted to hear My Funny Valentine played before the ceremony. Before the wedding I wasn't sure if you'd have time to work out an arrangement, but I'm glad you did.
Thanks also for all your help with planning the music and sticking to the Wagner march. Everything was just wonderful.
Best regards,
John
