Answer the question at the end by quoting:

Black Sabbath were an English rock band, formed in Birmingham in 1968, by guitarist and main songwriter Tony Iommi, bassist and main lyricist Geezer Butler, singer Ozzy Osbourne, and drummer Bill Ward. Black Sabbath are often cited as pioneers of heavy metal music. The band helped define the genre with releases such as Black Sabbath (1970), Paranoid (1970) and Master of Reality (1971). The band had multiple line-up changes, with Iommi being the only constant member throughout its history.
While Ozzy Osbourne was working on new solo album material in 2006, Rhino Records released Black Sabbath: The Dio Years, a compilation of songs culled from the four Black Sabbath releases featuring Ronnie James Dio. For the release, Iommi, Butler, Dio and Appice reunited to write and record three new songs as Black Sabbath. The Dio Years was released on 3 April 2007, reaching number 54 on the Billboard 200, while the single "The Devil Cried" reached number 37 on the Mainstream Rock Tracks chart. Pleased with the results, Iommi and Dio decided to reunite the 1981 Mob Rules era line-up for a world tour. While the line-up of Osbourne, Butler, Iommi and Ward were still officially called Black Sabbath, the new line-up opted to call themselves Heaven & Hell, after the album of the same name, to avoid confusion. When asked about the name of the group, Iommi stated "it really is Black Sabbath, whatever we do... so everyone knows what they're getting [and] so people won't expect to hear 'Iron Man' and all those songs. We've done them for so many years, it's nice to do just all the stuff we did with Ronnie again." Ward was initially set to participate, but dropped out before the tour began due to musical differences with "a couple of the band members". He was replaced by former drummer Vinny Appice, effectively reuniting the line-up that had featured on the Mob Rules (1981) and Dehumanizer (1992) albums.  Heaven & Hell toured the U.S. with openers Megadeth and Machine Head, and recorded a live album and DVD in New York on 30 March 2007, titled Live from Radio City Music Hall. In November 2007, Dio confirmed that the band had plans to record a new studio album, which was recorded in the following year. In April 2008 the band announced the upcoming release of a new box set and their participation in the Metal Masters Tour, alongside Judas Priest, Motorhead and Testament. The box set, The Rules of Hell, featuring remastered versions of all the Dio fronted Black Sabbath albums, was supported by the Metal Masters Tour. In 2009, the band announced the name of their debut studio album, The Devil You Know, released on 28 April.  On 26 May 2009 Osbourne filed suit in a federal court in New York against Iommi alleging that he illegally claimed the band name. Iommi noted that he has been the only constant band member for its full 41-year career, and that his bandmates relinquished their rights to the name in the 1980s, therefore claiming more rights to the name of the band. Although, in the suit, Osbourne was seeking 50% ownership of the trademark, he said that he hoped the proceedings would lead to equal ownership among the four original members.  In March 2010, Black Sabbath announced that along with Metallica they would be releasing a limited edition single together to celebrate Record Store Day. It was released on 17 April 2010.  Ronnie James Dio died on 16 May 2010 from stomach cancer. In June 2010, the legal battle between Ozzy Osbourne and Tony Iommi over the trademarking of the Black Sabbath name ended, but the terms of the settlement have not been disclosed.

How successful was the new group?

The Dio Years was released on 3 April 2007, reaching number 54 on the Billboard 200,

IN: Ernest Edward "Ernie" Kovacs (January 23, 1919 - January 13, 1962) was an American comedian, actor, and writer. Kovacs's visually experimental and often spontaneous comedic style influenced numerous television comedy programs for years after his death. Many individuals and shows, such as Johnny Carson, David Letterman, Rowan and Martin's Laugh-In, Saturday Night Live, Monty Python's Flying Circus, Jim Henson, Max Headroom, Chevy Chase, Conan O'Brien, Jimmy Kimmel, Captain Kangaroo, Sesame Street, The Electric Company, Dave Garroway, Uncle Floyd, and many others have credited Kovacs as an influence. Chevy Chase thanked Kovacs during his acceptance speech for his Emmy award for Saturday Night Live.

A frequent critic of the U.S. tax system, Kovacs owed the Internal Revenue Service several hundred thousand dollars in back taxes, due to his simple refusal to pay the bulk of them. Up to 90% of his earnings were garnished as a result. His long battles with the IRS inspired Kovacs to invest his money in a convoluted series of paper corporations in the U.S. and Canada. He would give them bizarre names, such as "The Bazooka Dooka Hicka Hocka Hookah Company". In 1961, Kovacs was served with a $75,000 lien for back taxes; that same day he bought the California Racquet Club with the apparent hope of being able to use it as a tax write-off. The property had mortgages at the time of purchase which were later paid by Edie Adams.  His tax woes also affected Kovacs's career, forcing him to take any offered work to pay his debt. This included the ABC game show Take A Good Look, appearances on variety shows such as NBC's The Ford Show, Starring Tennessee Ernie Ford, and some of his less memorable movie roles. He also filmed an unaired 1962 pilot episode for a proposed CBS series, Medicine Man (co-starring Buster Keaton, pilot episode titled "A Pony For Chris"). Kovacs's role was that of Dr. P. Crookshank, a traveling medicine salesman in the 1870s selling Mother McGreevy's Wizard Juice, also known as "man's best friend in a bottle". This was abandoned after his death, which occurred the day after filming some scenes for the pilot in Griffith Park. CBS initially intended to broadcast the show as part of a summer replacement program, The Comedy Spot, but decided against it due to problems with Kovacs's estate. The pilot is part of the public collection of the Paley Center for Media.  Some of the issues regarding Kovacs's tax problems were still unresolved years after his death. Kovacs had purchased two insurance policies in 1951; his mother was named as the primary beneficiary of them. The IRS placed a lien against them both for their cash value in 1961. To stop the actions being taken against her, Mary Kovacs had to go to Federal court. The court's early 1966 ruling resolved the issue, with the last sentence of the document reading: "Prima facie, it looks as if, within the limits of discretion permitted the government by the relevant statutes, an injustice is being done Mary Kovacs."  Adams, who married and divorced twice after Kovacs's death, refused help from celebrity friends who planned a benefit for the purpose. Saying "I can take care of my own children", and being determined to accept offers only from those who wanted to hire her for her talents, Adams managed to pay all of Kovacs' debts.

did eh do any other work?
