Context paragraphs:
Cats Under the Stars: Cats Under the Stars is an album by the Jerry Garcia Band.  Released in 1978, it is the only studio album credited to the band.  It was Jerry Garcia's first album on the Arista label and his first LP using the band name Jerry Garcia Band.  It includes only one song that was performed by the Grateful Dead.  Keith and Donna Godchaux, who were at the time members of the Garcia Band, contributed to the music.

Searching for Jerry Garcia: Searching for Jerry Garcia is the second and final studio album by Detroit rapper Proof of D12, released on August 9, 2005.  It was the only solo album that Proof released on a major record label before his death.  It reached number 65 on the U.S. "Billboard" 200 Albums Chart.  The album is named after Grateful Dead member Jerry Garcia.  The album's release date, August 9, 2005, intentionally coincided with the ten-year anniversary of Garcia's death.

Workingman's Dead: Workingman's Dead is the fourth Grateful Dead studio album.  It was recorded in February 1970 and originally released on June 14, 1970.  The album and its studio follow-up, "American Beauty", were recorded back-to-back using a similar style, eschewing the psychedelic experimentation of previous albums in favor of Jerry Garcia and Robert Hunter's Americana-styled songcraft.

China Cat Sunflower: "China Cat Sunflower" is a song performed by the Grateful Dead which was first recorded for their third studio album "Aoxomoxoa".  The lyrics were written by Robert Hunter and the music composed by Jerry Garcia.  The song was typically sung by Jerry Garcia.  The first live recording of this song appeared on Europe '72, paired (as was typical) with "I Know You Rider".  Lyrically, this song has many literary references, including Lewis Carroll's "Alice in Wonderland", George Herriman's "Krazy Kat", and Dame Edith Sitwell's "Polka".

Teach Your Children: "Teach Your Children" is a song by Graham Nash.  Although it was written when Nash was a member of the Hollies, it was never recorded by that group in studio (although a live recording does exist), and first appeared on the album "Déjà Vu" by Crosby, Stills, Nash & Young released in 1970.  The recording features Jerry Garcia on steel guitar.  Garcia did not know how to play the steel guitar.  He told Lon Goddard of the British music newspaper Record Mirror in an interview, that he recorded a series of pieces on the steel guitar and spliced them together in the studio to create the backing and solo.  Garcia had made an arrangement that in return for his playing steel guitar on "Teach Your Children," CSNY would teach the members of the Grateful Dead how to sing harmony for their upcoming albums, "Workingman's Dead" and "American Beauty".  Released as a single, the song peaked at #16 on the "Billboard" Hot 100 charts that year.  On the Easy Listening chart, "Teach Your Children" peaked at #28.  In Canada, "Teach Your Children" reached number 8.

A nine-track limited edition Vinyl LP was released on April 2016.  On August 1, 2016, studio recordings of "Deep Elem Blues" and "Half-Step Mississippi Uptown Toodeloo" were released digitally, to coincide with Garcia's birthday.  A live show recording was released digitally in April 2017 as "The Promised Land at The Deanery, Brooklyn NY 3-23-2017".

Proof (rapper): DeShaun Dupree Holton (October 2, 1973 – April 11, 2006), better known by his stage name Proof, was an American rapper and actor from Detroit, Michigan.  During his career, he was a member of the groups 5 Elementz, Funky Cowboys, Promatic, Goon Sqwad and most notably, D12.  He was a close childhood friend of rapper Eminem, who lived on the same block, and was often a hype man at his concerts.  In 2006, Proof was shot and killed during an altercation at the CCC nightclub in Detroit.

Planet Earth Rock and Roll Orchestra (album): Planet Earth Rock and Roll Orchestra is the final solo album by Paul Kantner and the only Kantner solo release to be solely credited to the singer-songwriter.  The title comes from an unofficial name for San Francisco artists who recorded on various albums in 1970–1973, also known as PERRO.  "The Mountain Song" is dedicated "to David C, Jerry G, Graham N, Grace S, David F, Billy K and Mickey H and to one summer when all of our schedules almost didn't conflict," and was written during the 1970s recording sessions by Kantner and Jerry Garcia.  On the album, Kantner utilizes many of his collaborators and family members to front an extended musical trip similar to his then-recent Jefferson Starship efforts.

St. Stephen (song): "St. Stephen" is a song by the Grateful Dead, written by Jerry Garcia, Phil Lesh and Robert Hunter and originally released on the 1969 studio album "Aoxomoxoa".  The same year, a live version of the song was released on "Live/Dead", their first concert album.  Unlike the studio version, live versions usually included a section of the song called the "William Tell Bridge", which was used to segue into "The Eleven".  After being played frequently in live concerts from the late 1960s to the early 1970s, the song fell out of regular performance; subsequent live performances of St. Stephen were thus considered a special event by deadheads.
