The following appeared in the Musical Times in 1913:
An amusing story, for the truth of which we can vouch, comes to us from Toronto. An organist had drawn up the order of a Sunday service, and it was in type ready for printing, when the death of an important personage made a change necessary. The organist telephoned to the printer, and instructed him to change the Postlude to “Funeral March by Chopin.” This is what he found at the end of the list when he arrived at the church:“A few remarks by Chopin.”
The printed sheet is before us as we write (July 1913).
