My wife and I hired ourselves out as a violin/piano duo for weddings while we were in Plymouth. One wedding was at a beautiful posh hotel in the Devon countryside. The intention was to have the wedding ceremony outside, but the weather was proving to be very changeable. What followed resembled a scene from a carry on film; several times the hotel staff set up bows/ribbons etc. outside then quickly had to take them in when the rain came on. Then when the rain stopped, the hotel manager (claiming he had never had to change an outside venue for a wedding before) insisted that the staff yet again set up for an outdoor ceremony. Of course, we had to do the same with our electric piano - in out, in out etc. At one point we even started playing - the wind was blowing our pages all over the place, then the rain started again. Finally the decision was made to have the ceremony indoors, resulting in another top-speed transfer of items inside!
I said to my wife, 'It's just as well the bride hasn't seen what's been going on'. We learned afterwards that she was in her room in the hotel watching the whole sequence of events unfold before her!
Anyway, everything went fine after that, and the Bride didn't seem at all distressed. (Fortunately the rain didn't cause our piano to 'blow up' either!)
So the moral of my ramblings is -: check the weather forecast before agreeing to play outside!
