Someone told this story on Patrick Mead's blog:
I love the cell phone story Rubel Shelly told with respect to his phone going off at a Funeral Home as he was giving the eulogy. He said he apologized to the Funeral Home Director. The Funeral Home Director told him that wasn’t nearly as bad as what had happened at a previous funeral earlier that week. This was the funeral of a prominent woman in Nashville who happened to love the “Wizard of Oz.” It was her request that “Somewhere Over the Rainbow” be played at her funeral. When it came time to play her song the wrong song was selected so instead of “Somewhere Over the Rainbow,” “Ding-dong, the Wicked Witch is Dead” came blaring out!
