I played for just shy of an hour in total. For 30 minutes prior to the ceremony, I played a mix of stately marches and slow airs. Wedding music prior to the ceremony is usually more low-key. One new tune that I did play was "The Highland Wedding". This six-part march has taken me a fair amount of time to learn, but it went off pretty well. Well, the fourth part was a bit rocky both times that I played it. But, I may be the only person who knew. That's not always too comforting, though it should be. I also played for about 30 minutes after the ceremony. Those tunes were more light and upbeat, like "Crossing the Minch" or "Itchy Fingers". A number of quick marches and strathspeys were also played. The bottom line -- most of these tunes could inspire gleeful dancing.
I was pretty nervous prior to driving the winery. It has been a while since I have played at a wedding, but it was mostly because I was not just playing at any wedding, but at a ceremony where I was in some way representing the heritage of the groom. I could have brushed this off, but I probably took it too seriously instead. Since I did not know him or his family prior to arriving at the ceremony, he could have been related to some long line of amazing pipers for all I knew and would be listening in for any missed notes or chanter squeaks. Fortunately, so far as I know, this was no the case. He was very gracious and welcoming and made me feel very at-ease.
