Context: Chelsea Horror Hotel: A Novel is a 2001 novel by Dee Dee Ramone, a member of the punk band The Ramones.  It was released 13 months before Dee Dee died due to a heroin overdose.  The book follows Dee Dee as he dictates daily events at the Hotel Chelsea in New York City with his wife Barbra and dog Banfield.  Dee Dee is convinced that the room he stays in is the same where his old friend Sid Vicious killed his girlfriend, Nancy Spungen.  Dee Dee is further visited by other dead punks, including Johnny Thunders and Stiv Bators. Douglas Glenn Colvin (September 18, 1951 – June 5, 2002), known professionally as Dee Dee Ramone, was a German-American musician, singer and songwriter best known as founding member, songwriter, bassist and occasional lead vocalist for the punk rock band the Ramones. "Rockaway Beach" is a song by the American punk rock band the Ramones from their 1977 album "Rocket to Russia".  The song was written by bassist Dee Dee Ramone in the style of the Beach Boys and early surf rock bands.  The song is about Rockaway Beach, Queens, where Dee Dee liked to spend time.  Guitarist Johnny Ramone claimed that Dee Dee was "the only real beachgoer" in the group.  Released in 1977, it was the Ramones' highest-charting single in their career, peaking at number 66 on the "Billboard" Hot 100.  In June, 2013, the song was used in a radio ad campaign sponsored by Queens Economic Development Corporation to promote recovery from Hurricane Sandy by drawing New Yorkers back to Rockaway Beach.

Animal Boy is the ninth studio album released by the American punk band the Ramones through Sire Records on May 19, 1986.  Due to conflicts within the group, the album features less of lead singer Joey Ramone, both in performing and writing, and less of lead guitarist Johnny Ramone.  Bassist Dee Dee Ramone wrote and sang more on this album than previous albums, and Richie Ramone became the first drummer to write songs for the band.  The album spawned four singles, all of which charted on the UK Singles Chart.  In addition to singles, the band promoted their album by making a music video which parodied the benefit concerts Live Aid and Hands Across America. Dee Dee Ramone and the Chinese Dragons was a band fronted by former Ramones bassist Dee Dee Ramone.  It was formed in March 1992, and was the second post-Ramones band for Dee Dee, following Dee Dee Ramone and the Spikey Tops.  The band was made up of Ramone on guitar and vocals, former Liars, Cheats and Thieves members Richie Screech (aka Richie Karaczynski) and Alan Valentine on guitar and bass respectively, and Scott Goldstein on drums.  In the band's short time together, they only released one 7" single which featured an original song on the a-side and a cover of the New York Dolls' "Chatterbox" on the b-side.  Ramone's next project after this was Dee Dee Ramone I.C.L.C. Dum Dum Girls are an American rock band, formed in 2008.  It began as the bedroom recording project of singer and songwriter Dee Dee (née Kristin Gundred).  She is currently based in New York City.  The name is a double homage to the Vaselines' album "Dum Dum" and the Iggy Pop song "Dum Dum Boys".  Critics initially assumed that Dee Dee's stage name was inspired by Dee Dee Ramone, but she stated that this was not true; it was her mother's name, which she took as her middle name after her mother's death.  The last name "Penny" was erroneously provided by British music magazine "NME". The Ramainz were a U.S. tribute band to the Ramones.  Its members included Dee Dee Ramone, Marky Ramone, Dee Dee's wife Barbara Zampini (also known as Barbara Ramone) and C. J. Ramone.

They released one live album entitled "Live in N.Y.C." on 8 October 2002, four months after Dee Dee Ramone's death on 5 June. Youth Gone Mad featuring Dee Dee Ramone is a collaboration studio album by the American punk band the Youth Gone Mad and former Ramones bassist Dee Dee Ramone.
