Background: Abbot Howard Hoffman (November 30, 1936 - April 12, 1989) was an American political and social activist, anarchist, and revolutionary who co-founded the Youth International Party ("Yippies"). Hoffman was arrested and tried for conspiracy and inciting to riot as a result of his role in protests that led to violent confrontations with police during the 1968 Democratic National Convention, along with Jerry Rubin, David Dellinger, Tom Hayden, Rennie Davis, John Froines, Lee Weiner, and Bobby Seale. The group was known collectively as the "Chicago Eight"; when Seale's prosecution was separated from the others, they became known as the Chicago Seven. While the defendants were initially convicted of intent to incite a riot, the verdicts were overturned on appeal.
Context: Hoffman was arrested and tried for conspiracy and inciting to riot as a result of his role in anti-Vietnam War protests, which were met by a violent police response during the 1968 Democratic National Convention in Chicago. He was among the group that came to be known as the Chicago Seven (originally known as the Chicago Eight), which included fellow Yippie Jerry Rubin, David Dellinger, Rennie Davis, John Froines, Lee Weiner, future California state senator Tom Hayden and Black Panther Party co-founder Bobby Seale (before his trial was severed from the others).  Presided over by Judge Julius Hoffman (no relation to Hoffman, about which he joked throughout the trial), Abbie Hoffman's courtroom antics frequently grabbed the headlines; one day, defendants Hoffman and Rubin appeared in court dressed in judicial robes, while on another day, Hoffman was sworn in as a witness with his hand giving the finger. Judge Hoffman became the favorite courtroom target of the Chicago Seven defendants, who frequently would insult the judge to his face. Abbie Hoffman told Judge Hoffman "you are a 'shande fur de Goyim' [disgrace in front of the gentiles]. You would have served Hitler better." He later added that "your idea of justice is the only obscenity in the room." Both Davis and Rubin told the Judge "this court is bullshit." When Hoffman was asked in what state he resided, he replied the "state of mind of my brothers and sisters".  Other celebrities were called as "cultural witnesses" including Allen Ginsberg, Phil Ochs, Arlo Guthrie, Norman Mailer and others. Hoffman closed the trial with a speech in which he quoted Abraham Lincoln, making the claim that the president himself, if alive today, would also be arrested in Chicago's Lincoln Park.  On February 18, 1970, Hoffman and four of the other defendants (Rubin, Dellinger, Davis, and Hayden) were found guilty of intent to incite a riot while crossing state lines. All seven defendants were found not guilty of conspiracy. At sentencing, Hoffman suggested the judge try LSD and offered to set him up with "a dealer he knew in Florida" (the judge was known to be headed to Florida for a post-trial vacation). Each of the five was sentenced to five years in prison and a $5,000 fine.  However, all convictions were subsequently overturned by the Seventh Circuit Court of Appeals. The Walker Commission later found that in fact it had been a "police riot".
Question: What happened that they became known as the Chicago Seven rather than Eight?
Answer: 

Problem: Background: King Diamond are a Danish heavy metal band formed in 1985 by vocalist King Diamond, guitarists Andy LaRocque and Michael Denner, bassist Timi Hansen and drummer Mikkey Dee. Diamond, Denner and Hansen had recently departed the group Mercyful Fate, and decided to form a new band under the King Diamond moniker, as it was already known from the Mercyful Fate days. In 1986, King Diamond released their debut album Fatal Portrait. Since then the band have released a total of twelve studio albums (most of them concept albums), two live albums, two extended plays, five compilations and five singles.
Context: In June 1990, King Diamond began recording fifth studio album at Sweet Silence Studios in Copenhagen, Denmark. The drums on the album were played by Snowy Shaw using drum pads. Released on October 30, 1990, The Eye debuted at number 179 on Billboard 200. However, the band did not tour in support of the album, due to lack of label support. Following The Eye, Hal Patino and Pete Blakk were replaced by Sharlee D'Angelo and Mike Wead respectively. However this line-up ended-up not recording any material, as vocalist King Diamond reunited with Mercyful Fate in 1993 (King Diamond would balance recording and touring with both Mercyful Fate and his eponymous band throughout the 1990s).  After recording and touring with Mercyful Fate, King Diamond reformed his eponymous band in 1994. With the line-up of King Diamond, Andy La Rocque, as well as guitarist Herb Simonsen, bassist Chris Estes and drummer Darrin Anthony, the band spent September through October, 1994, recording their next album. Released on June 6, 1995, The Spider's Lullabye was the band's first album on Metal Blade Records, as well as their first studio release since Fatal Portrait to not be a concept album. The album went on to peak at number 31 on the Finnish album charts. In March 1996, King Diamond began recording their seventh studio album at the Dallas Sound Lab. Released on October 1, 1996, The Graveyard saw King Diamond returning to writing concept albums. The album also charted at number 23 in Finland. After the album's release, drummer Darrin Anthony was forced to leave the band due to a car accident and was subsequently replaced by John Luke Hebert.  On February 24, 1998, King Diamond released the album Voodoo, which charted at number 27 on the Finnish album chart and at number 55 on the Swedish album chart. After the album's release, guitarist Herb Simonsen was replaced by Glen Drover. When Mercyful Fate was put on hold in 1999, King Diamond began recording the album House of God at the Nomad Recording Studio in Carrollton, Dallas, Texas, with their new bassist Paul David Harbour, who had replaced Chris Estes. Released on June 20, 2000, the album peaked at number 60 in Sweden. After the album's release, guitarist Glen Drover and drummer John Luke Hebert were replaced by Mike Wead and Matt Thompson respectively.
