OK, why not put it here too? The more that this question is throughout the Internet, the better, perhaps? This question had been in the "I Need to Know" forum at IMDb, where I was helped by the users WillEd, Byrdz, and Helena727 in particular. Unfortunately, we were unable to come up with a response. It was a long thread, so, though I'll only be posting the gist of the thread, I'll still be posting here in parts. Here goes; here's my first post only from a few months ago, but seemingly so long! _______________________________________________________ I'm sure somebody has posted about this before because it's seemingly such a big mystery (see www.soundtrackcollector.com/forum/displayquestion.php?topicid=7598, en.allexperts.com/q/Classic-Film-2786/Cole-Porter-Sleuth-movie.htm, and www.imdb.com/title/tt0069281/board/thread/10107549), so, if there is another thread about this, it would help me a great deal if someone can post a link to it. The mystery is that just about no one seems to know who sang three Cole Porter songs--"Just One of Those Things," "You Do Something to Me," and "Anything Goes"--in the movie Sleuth (1972). Here's a link to a video of Laurence Olivier's character dancing to them in a scene from the movie: www.youtube.com/watch?v=4_VVr8ScGOc. One would think that by this time someone would have some idea of who sang them, but the identity of the singer just seems a mystery despite some promising leads over the years, none of which have panned out. Even more curiously, there is no singer identified in the end credits, and the three songs did not appear on the movie's soundtrack. From what I could find, the last time that someone could look into this question was at the website "Soundtrack Collector" on March 5 of this year; the last poster stated that he had found "the exact song" of "Anything Goes" on Amazon Music for $1.29. After checking Amazon Music and looking through/previewing the many different versions of "Anything Goes," I was unable to find the song to which he referred and could not find the version from Sleuth. The poster immediately before him suggested that "You Do Something to Me" was on the soundtrack for Woody Allen's Magic in the Moonlight, but, after checking that, I discovered that that version was sung by Frank Luther for Leo Reisman's orchestra, a candidate considered since the beginning--and not the actual singer from Sleuth. The weird thing about the whole thing is that it seems so mysterious. Why should it be so difficult to find who sang three songs? Why wasn't the singer's name in the credits? Why didn't the soundtrack include the songs? My only guess--and I concede that this is far-fetched--is that it's on purpose. The film is all about tricks, games, mysteries, puzzles, etc., and, unlikely as it sounds, I wonder if director Joseph Mankiewicz and screenwriter Anthony Shaffer made this mysterious singer so hard to find on purpose. That is to say, I wonder if the versions were specially created for the film or put together from other recordings (somehow)--or that it's someone whom we wouldn't suspect of being a singer (someone suggested Michael Caine himself, though I very much doubt it). More likely, of course, no one ever thought that anyone would be trying so hard to find this guy--but that still leaves the above questions unanswered. I apologize for going on so long, but I did want to provide all the background that I could. Thank you all very much--it would be great if someone could finally put this old question to rest!
