Geronimo Jackson is a band whose album is found in the Swan's music library by Charlie and Hurley . Charlie, as an expert in "all things musical”, says that he has never heard of them. ("The Hunting Party")
- Producers Damon Lindelof and Carlton Cuse seemed to suggest that the band was real. "They're a band not a lot of people have heard about. They just pressed one very obscure album in the mid to late '70s". (Official Lost Podcast/January 09, 2006)
- The producers claimed that it was indeed a real, very obscure, band from the '70s. (Official Lost Podcast/May 15, 2006)
In The Lost Experience
- Part of the audio that played when the Hanso Phone Line was called (it now appears to be shut down) involved a Danish DJ playing "classic rock from the '60s and '70s including an exclusive recording by Geronimo Jackson's first complete album, Magna Carta." (Text is translated)
- In his June 26, 2006 podcast DJ Dan commented "Anyway, point is, Rachel's blog is pleasant, but I don't have the time to be finding out which Geronimo Jackson song little Suzy Cornbelt is listening to when she misses her mommy!"
- In her Italy 05 blog entry, Rachel lamented, "You know that Geronimo Jackson tune? It goes 'She left me on the boardwalk/With my head held in my hands...' Well, it's been running through my head all day, over and over, and over."
- In DJ Dan's First Live Podcast of August 11, 2006, Dan identified Keith Strutter as the guitarist and founder of Geronimo Jackson, and noted that Strutter's previous band was called the Karma Imperative. He also said that Strutter started Geronimo Jackson in the '60s.
- During DJ Dan's 7/05 podcast, a listener by the name of Anthony called in saying that in the 70s his grandmother joined what he thought was a cult by the name "KARMA Imperative", although he probably meant to say the DHARMA Initiative but simply misspoke the name. According to Anthony's story, his grandmother joined the "KARMA Imperative" while attending the University of Michigan and was taken to an unknown location in the South Pacific and was never seen again, declared dead.
- In his Second Live Podcast of September 24, 2006, Dan more or less conceded that the band's original album Magna Carta would be very difficult to locate, calling it "an incredibly rare pressing".
- In a response to an inquiry at Notes from the Experience LiveJournal dated September 27, 2006, Javier Grillo-Marxuach further elaborated on DJ Dan's comments from the Second Podcast by saying that Geronimo Jackson "stuff is very arcane and hard to find, frankly, I'm surprised we managed to score a copy to get on the show...I think the Danish DJ was actually playing a bootleg". He also confirmed that only Edward Kitsis and Adam Horowitz would be able to identify which of the individuals on the cover of Magna Carta was Keith Strutter, or who was responsible from the Lost production team for getting a copy of the album into the Hatch for use on Lost.
On the Season 2 DVD
An easter egg on Disc 4 of the Season 2 DVD features a short video clip of supervising producers Edward Kitsis and Adam Horowitz elaborating on the band's backstory. They claim it was the brainchild of Keith Strutter, a Kentuckyan who ran away from home in the 1960s and wound up in San Francisco. The band's first gigs were at burlesque shows, working their way up to play clubs like the Avalon and the Filmore. They never headlined, but put out one album - Magna Carta - which has been out of print for some time. Kitsis claims that the band disappeared into obscurity in Woodstock, NY in 1971. It was put into Lost as a tribute to an under-appreciated band.
- On January 19th 2006 a fanmade website appeared at www.geronimo-jackson.com. It was removed after a few months.
- The album title Magna Carta anagrams to "Anagram act."
- Charlie's middle name is "Hieronymus", a foreign variant of the name "Geronimo".
