Charlie Chaplin Meets Harry Lauder

This is an incomplete, then unreleased, and untitled charity film featuring Charlie Chaplin and Harry Lauder. Wikipedia and IMDb lists the film's year as 1918. http://www.jimvallance.com/02-family-folder/harry-lauder-folder/lauder-pages/harry-lauder-films/pg-lauder-films.html lists the filming date as January 22, 1917. That is the date used here. IMDb lists the writer and director as Harry Lauder. Those credits and producer's credit are given to Chaplin by Wikipedia. Seeing as Wikipedia doesn't discredit Lauder, it's presumed here that both co-wrote and directed the film and Chaplin himself produced it.
