The latest in pre-planned funeral services

A friend sings at funerals. Recently, the secretary from the local parish calls my friend on a Sunday evening and asks if she'd be available for a funeral on Tuesday.
My friend says that she is available.
"There's just one thing," says the secretary. "The person isn't dead yet."
They both agree that this is one of the more unusual requests.
During the day on Monday, my friend checks with the church secretary. Nope, still not dead.
The afternoon drags along into evening. The church secretary calls, "OK, we're all set. The person died."
With no wake and a graveside services later, the funeral went on as scheduled on Tuesday morning.
