Knowing the venue, it doesn't seem that daft - it's a pleasant enough place (if you ignore the gravestones ...) My main issue would be the utter incompatibility of the demeanour of the guests attending the events - after all a funeral is something of a celebration of the life of the deceased, whereas a wedding is a much more sombre occasion ...
Paints a picture though, Barmaid....you in your finery....at the crem...getting wed with an Aldi plastic bag rattling and clinking on your arm..... ;-)
