Sat and read through whole of your first thread last night. Had few ideas to add but others beat me to it - namely the cheese wedding cake. We had one and it was lovely, worked out about £85 for 5 tiers and there was LOADS of cheese left over! We also hired a jukebox as a cheap alternative to a band - or the legion might have one? Just keep the tweenagers off it or at least clear their crap selection occasionally
If you're still looking for ceremony music, check out yiruma "river flows in you". It's a beautiful piano piece which I walked down the 'aisle' to, so slightly biased and we just downloaded it and played via iPod.
