My fiance and I want to have Sufjan Stevens' 'Chicago' and WHY?'s 'Gemini Birthday Song' used for our wedding, but only without vocals.

If anyone can give me info. on the possibility of this i'd be indebted.

Better yet, if someone managed to do it for me and e-mailed me the files I would love you forever and save you a hot-dog from the barbecue.
