Former vaudevillian and amateur filmmaker Sid Laverents wrote, directed and starred in , a short film from 1970 that features a dozen Split Screens of him playing a variety of musical instruments simultaneously. Each of Laverents's musicians displays a different character with its own costume and hairstyle as they unite to perform the song "Nola," a novelty ragtime number popularized in the 1920s. Coupling his own ingratiating persona, painstaking in-camera multiple exposures and complex overdubbing, Laverents created a film that may be amateur but not amateurish.

 was added to the National Film Registry in 2000.


 * Film within a Film: There is another short film entitled "Multiple Sidosis" completely embedded within the larger film, which is made in the course of the outer film.
 * Highlighted Text: The bit of the reel-to-reel recorder's instruction manual which inspires Sid is emphasized in this way.
 * Hollywood Giftwrap: Averted.  The gifts under the tree all appear to be conventionally wrapped, and Sid tears the wrapping off his biggest gift.
 * Music Video
 * Name's the Same: That "SNL" at the beginning isn't for Saturday Night Live.
 * Other Common Music Video Concepts: Even though he lacks an actual studio, this is very much an "In The Studio" video.
 * Overcrank: The audio version is done to create pair of Alvin and the Chipmunks-style backing vocals at one point.
 * Paper-Thin Disguise: Sid frequently changes his "look" when there are multiple similar instances of him on the screen, by combing his hair differently, wearing glasses, or putting on a hat.  (Or Mickey Mouse ears and whiskers.)
 * Performance Video
 * Self-Backing Instrumentalist and Vocalist: Sid plays all the instruments and sings all the vocal parts.
 * Short Film: Including the credits at the start, it's less than nine and a half minutes long.
 * Split Screen: Up to a dozen separate images at one time appear on the screen; the method involved appears very simple and crude, being basically multiple exposures with masks around each individual shot.
 * Unintentional Period Piece: Everything about this short film practically screams "1970".
