I blew the chanter out of the bag once at a funeral. That was embarrassing.
A different time, a visitation/viewing was to start at 4 pm at the funeral home, which is about 5 miles from the cemetery, so I got to the cemetery at approx. 4:00, thinking I had plenty of time. The family had decided skip the visitation and go straight to the cemetery, but no one bothered to tell the 'piper. I pulled in to the cemetery to find the hearse, family, casket, military honor guard and flower van already there. That one wasn't my fault, but it felt like it.
I've been nervous and rushed tunes, and played wrong notes, and been too dry, and had squirrely drones, but nothing to compare to forgetting the 'pipes at home.

By the way, I think the aforementioned quarry is near Mt. Airy. It's where they quarried white granite to build monuments, bridges, and curbs for streets in New England states that use a lot of salt to melt snow in the winter. The salt would eat concrete, but it won't harm granite. I saw it on television not too long ago.
