The Charlie Chaplin Cocktail was one of the premier drinks of the Waldorf-Astoria prior to 1920. The equal mix of lime, apricot brandy and sloe gin is documented in A.S. Crockett's "The Old Waldorf-Astoria Bar Book" and it's a nice gentle mix, although rather thick and sweet. Of course, the drink is named in honor of the famous actor Charlie Chaplin, but it's unclear if the drink made it into the comedian's repertoire.
You may also be interested in a cocktail named for one of Chaplin's wives, the Lita Grey. It also includes sloe gin and the two make better companions than their namesakes.
