"Holdin' Onto Somethin'" is a song written by Tom Shapiro and Thom McHugh, and recorded by American country music artist Jeff Carson.
 It was released in March 1996 as the fourth single from his debut album "Jeff Carson".

Jeffrey Charles "Jeff" Ragsdale ( ) is an American author, documentary filmmaker, actor and stand-up comedian.
 In 2011 he posted a flyer in New York City as a "social experiment", stating his phone number and asking people to call him, describing himself as "Jeff, one lonely guy".
 He was overwhelmed with thousands of calls after photos of the flyer were posted on the internet.
 The experience led to his 2012 book "Jeff, One Lonely Guy", and indirectly to a 2013 pilot episode for a reality television show, "Being Noticed", and a starring role in the 2014 documentary "Hotline".
Film gris (French for "grey film"), a term coined by Thom Andersen, is a type of film noir which categorizes a unique series of films that were released between 1947 and 1951.
 They came in the context of the first wave of the communist investigations of the House Un-American Activities Committee.
Los Angeles Plays Itself is a video essay by Thom Andersen, finished in 2003, exploring the way Los Angeles has been presented in movies.
 Consisting almost entirely of clips from other films with narration, the film was not initially released commercially.
 The film was only seen in screenings presented by Andersen, occasional presentations at American Cinematheque and copies distributed via filesharing and other person-to-person methods.
 In 2014, it was announced that the film would finally be released officially by Cinema Guild.
Stupid Teenagers Must Die!
 (early title "Blood & Guts") is a 2006 spoof film directed by Jeff C. Smith and written by Smith and Curtis Andersen.
 During production and initial festival screenings, the film was titled "Blood & Guts", but before sending it to distributors, the change to the current title was made to better reflect the humor intended by the filmmakers, as they thought the original title implied more carnage than the film supplied.
Eadweard Muybridge, Zoopraxographer is a 1975 documentary film directed by Thom Andersen about the English photographer Eadweard Muybridge.
Jeff, One Lonely Guy is a 2012 nonfiction book by Jeff Ragsdale.

 In 2014 Amitava Kumar included portions of "Jeff, One Lonely Guy" in his newly released book, "A Matter of Rats: A Short Biography of Patna".
 Kumar previously interviewed Ragsdale and wrote about him in "The New York Times".
