input: In early 1997, Carl was diagnosed with lung and brain cancer after years of heavy smoking. Despite his terminal condition, Carl continued to perform with the band on its 1997 summer tour while undergoing chemotherapy. During performances, he sat on a stool and needed oxygen after every song. However, Carl was able to stand when he played on "God Only Knows". Carl died on February 6, 1998, two months after the death of the Wilsons' mother, Audree, leaving Brian, Jardine and Love as the three remaining original members. Following Carl's death, the remaining members splintered. Love and Johnston, occasionally with David Marks, continued to tour together, initially as "America's Band", but following several cancelled bookings under that name, they sought authorization through Brother Records Inc. (BRI) to tour as "The Beach Boys" and secured the necessary license. In turn, Jardine left the band and began to tour regularly with his band "Beach Boys: Family & Friends" until he ran into legal issues for using the name without license. Meanwhile, Jardine sued Love, claiming that he had been excluded from their concerts. BRI, through its longtime attorney, Ed McPherson, sued Jardine in Federal Court. Jardine, in turn, counter-claimed against BRI for wrongful termination. BRI ultimately prevailed. Love and Johnston continued to tour as "The Beach Boys" with supporting musicians.  Brian Wilson sought treatments for his illnesses that aided him in his solo career. He toured regularly with his backing band consisting of members of Wondermints and other LA/Chicago musicians. Marks also maintained a solo career. The surviving group members appeared as themselves for the 1998 documentary film Endless Harmony: The Beach Boys Story, directed by Alan Boyd. Following the success of 1997's The Pet Sounds Sessions, many compilations were then issued by Capitol containing new archival material: Endless Harmony Soundtrack (1998), Ultimate Christmas (1998), and Hawthorne, CA (2001).  In 2004, Wilson recorded and released his solo album Brian Wilson Presents Smile, a reinterpretation of the Smile project that he initiated with the Beach Boys 36 years earlier. That September, Wilson issued a free CD through the Mail On Sunday that included Beach Boys songs he had recently rerecorded, five of which he co-authored with Love. The 10 track compilation had 2.6 million copies distributed and prompted Love to file a lawsuit in November 2005; he claimed the promotion hurt the sales of the original recordings. Love's suit was dismissed in 2007 when a judge determined that there were no triable issues.  On June 13, 2006, the five surviving Beach Boys (Wilson, Love, Jardine, Johnston, and Marks) appeared together for the celebration of the 40th anniversary of Pet Sounds and the double-platinum certification of their greatest hits compilation, Sounds of Summer: The Very Best of The Beach Boys, in a ceremony atop the Capitol Records building in Hollywood. Plaques were awarded for their efforts, with Wilson accepting on behalf of Dennis and Carl. Wilson began a brief Pet Sounds tour with Jardine later that year.

Answer this question "Did this affect his performance"

input: Sometime in 1971, new manager Miles Copeland III decided to re-organise the band, focussing on what he felt were Renaissance's strong points - Haslam's voice and Tout's piano. Will Romano in Mountains come out of the sky explained that "unlike many of the artists to which they were compared Renaissance allowed the piano and female voice to come to the forefront". Until then Haslam had shared vocals with Terry Crowe, who was in effect the band's chief vocalist. Crowe and Korner went, the former unreplaced, the latter replaced by a succession of bass players, including John Wetton (later of King Crimson, UK, and Asia), Frank Farrell (later in Supertramp) and Danny McCulloch (formerly of The Animals and a former bandmate of Dunford and Crowe in The Plebs), until the position settled with the inclusion of Jon Camp. It was also decided that Dunford would now concentrate on composing, and a new guitar player, Mick Parsons, was brought in for live work. In 1972, shortly before recording sessions for the new band's debut LP, drummer Terence Sullivan joined after Slade's initial replacement, Ginger Dixon, was deemed unsuitable following a European tour. Parsons died in a car accident and was replaced at short notice by Rob Hendry. The resulting line-up entered the studio having played only a dozen gigs together.  Prologue was released later in 1972 on EMI-Sovereign Records in the UK and on Capitol-Sovereign in North America. Prologue's music was, except for two songs by McCarty, composed by Dunford, with all lyrics by Thatcher-Newsinger. Rock radio stations (particularly in the northeast US and Cleveland) gave the song Spare Some Love significant airplay for a few months after the album's release, and fans of Yes and Emerson, Lake & Palmer in particular, took notice of the band. Francis Monkman, of the group Curved Air (another group managed by Copeland), was a guest on VCS3 synthesiser on the final track "Rajah Khan".  Hendry was replaced for the Prologue tour by Peter Finberg, who in turn left the group shortly before the sessions for the next album. Michael Dunford then returned as (acoustic) guitarist, completing what most fans regard as the classic five-piece line-up, which would remain together through six studio albums. Ashes are Burning was released in 1973. Andy Powell, of the group Wishbone Ash, was brought in for a blistering electric guitar solo on the final track "Ashes are Burning", which became the band's anthem piece, extended to almost twenty minutes with a long bass solo and other instrumental workouts. (John Tout returned Powell's favour by playing organ on Wishbone Ash's 1972 album Argus.) The album became the band's first to chart in the US, where it reached No. 171 on the Billboard 200. The band played their first US concerts during that period, enjoying success on the East Coast in particular, which soon resulted in a special orchestral concert at New York's Academy of Music in May 1974. Soon Renaissance would choose to concentrate on the US market, as the UK press virtually ignored them.
