Question: Who is the sibling of Everybody's rockin's performer?

full_context: Document 1: Rockin' in the Free World: "Rockin' in the Free World" is a song by Neil Young, released on his 1989 album "Freedom". Two versions of the song were released, similarly to the song "Hey Hey, My My (Into the Black)" of Young's "Rust Never Sleeps" album, one of which is performed with a predominantly acoustic arrangement, and the other with a predominantly electric arrangement. The song is now considered one of Neil Young's best songs. The song was ranked 216 on Rolling Stone's 500 Greatest Songs of All Time.
Document 2: Jock Young: Jock Young was educated at the London School of Economics. His PhD was an ethnography of drug use in Notting Hill, West London, out of which he developed the concept of moral panic. The research was published as "The Drugtakers". He was a founding member of the National Deviancy Conferences and a group of critical criminologists in which milieu he wrote the groundbreaking, "The New Criminology: For a Social Theory of Deviance" in 1973, with Ian Taylor and Paul Walton and "The Manufacture of News" (with Stan Cohen).
Document 3: James Young (Upper Canada politician): He was born in Nova Scotia in 1777 and settled in Ameliasburgh Township in Upper Canada. In 1808, he was named justice of the peace in the Midland District. He served in the local militia during the War of 1812 and became lieutenant colonel in 1824. He represented Hastings & Ameliasburg in the 6th Parliament of Upper Canada. He died at Carrying Place in 1831.

Document 6: Rockin' Radio: Rockin' Radio is a 1983 album by Jazz trumpeter Tom Browne, released on Arista Records. It is his fifth overall album. His prior album, "Yours Truly" did have success on the charts, but no individual single charted. "Rockin Radio" was different. The album peaked at #24 on the R&B album charts and #147 on the Billboard 200 (both lower than "Yours Truly"), but the title track hit #11 on the R&B charts and #33 on the dance charts. "Crusin'" hit #63 on the R&B charts.
Document 7: Newborn (album): Guitarist Tommy Bolin and singer Roy Kenner left the band, and were replaced by guitarist Richard Shack and vocalist Bubba Keith. This album is notable for being perhaps the most boogie-based James Gang release and for featuring a cover of the Elvis Presley classic "Heartbreak Hotel".
Document 8: This Note's for You: This Note's for You is the 16th studio album by Canadian musician Neil Young, released on April 11, 1988 on Reprise. It was originally credited to "Young and the Bluenotes." Part of the album's concept centered on the commercialism of rock and roll, and tours in particular. (The title selection, specifically, is a hostile social commentary on concert sponsorship.) The music is marked by the use of a horn section. It also marked Young's return to the recently re-activated Reprise Records after a rocky tenure with Geffen Records.
Document 9: Short Sharp Shocked: Short Sharp Shocked is the second album by Michelle Shocked. Originally released in 1988, it was remastered and reissued in 2003 as a two-CD set by Shocked's own label, Mighty Sound. The title is a play on the phrase short, sharp shock. The record title and cover image is similar to that of the 1984 Chaos U.K. album "Short Sharp Shock".
Document 10: Scott Young (writer): Scott Alexander Young (April 14, 1918 – June 12, 2005) was a Canadian journalist, sportswriter, novelist and the father of musicians Neil Young and Astrid Young. Over his career, Young wrote 45 books, including novels and non-fiction for adult and youth audiences.
Document 11: William Young (Nova Scotia politician): Born in Falkirk, the son of John Young and Agnes Renny, Young was first elected to the Nova Scotia House of Assembly in 1836 as a Reformer (or Liberal) and, as a lawyer, defended Reform journalists accused of libel. When responsible government was instituted in 1848, Young hoped to become the first Premier but was passed over in favour of fellow reformer James Boyle Uniacke and Young became Speaker. However, Young succeeded Uniacke in 1854.
Document 12: Life (Neil Young & Crazy Horse album): Life is an album by Canadian musician Neil Young and his backing band Crazy Horse, and it is Young's last release on the Geffen label. As with their 1979 album "Rust Never Sleeps", Young and the Horse performed most of this album's songs live with the exceptions of "Cryin' Eyes" and "We Never Danced" which were recorded in studio. The album was released on July 6, 1987.
Document 13: John Walter Scott: John Walter Scott (November 2, 1845 – January 4, 1919) of New York City, was originally from England, but he emigrated to the United States to take part in the California Gold Rush. Unsuccessful at the prospecting trade, Scott began to sell postage stamps for collectors and in a short period of time became the nation's leading stamp dealer. During his lifetime, he was known as "The Father of American Philately" by his fellow stamp collectors.
Document 14: Nick Sagan: Nick Sagan (born September 16, 1970 in Boston, Massachusetts) is an American novelist and screenwriter. He is the author of the science fiction novels "Idlewild", "Edenborn", and "Everfree", and his screen credits include episodes of "" and "". He is the son of astronomer Carl Sagan and artist and writer Linda Salzman.
Document 15: Everybody's Rockin': Everybody's Rockin' is the 13th studio album by Canadian musician Neil Young, released on August 1, 1983. The album was recorded with the Shocking Pinks (a band made up just for the occasion), and features a selection of rockabilly songs (both covers and original material). Running 25 minutes, it is Young's shortest album. "Everybody's Rockin"' is typical of his 1980s period in that it bears little or no resemblance to the album released before it ("Trans" (1982), a synth-heavy, electro-rock album), nor the one released after it ("Old Ways" (1985), which is pure country).
