Some context: Sly and the Family Stone was an American band from San Francisco. Active from 1966 to 1983, the band was pivotal in the development of funk, soul, rock, and psychedelic music. The group's core line-up was led by singer-songwriter, producer, and multi-instrumentalist Sly Stone, and included Stone's brother and singer/guitarist Freddie Stone, sister and singer/keyboardist Rose Stone, trumpeter Cynthia Robinson, drummer Greg Errico, saxophonist Jerry Martini, and bassist Larry Graham. The band was the first major American rock group to have a racially integrated, male and female lineup.
With the band's new-found fame and success came numerous problems. Relationships within the band were deteriorating; there was friction in particular between the Stone brothers and Larry Graham. Epic requested more marketable output. The Black Panther Party demanded that Sly replace Gregg Errico and Jerry Martini with black instrumentalists and fire manager David Kapralik.  After moving to the Los Angeles area in fall 1969, Sly Stone and his fellow band members became heavy users of illegal drugs, primarily cocaine and PCP. As the members became increasingly focused on drug use and partying (Sly Stone carried a violin case filled with illegal drugs wherever he went), recording slowed significantly. Between summer 1969 and fall 1971, the band released only one single, "Thank You (Falettinme Be Mice Elf Agin)" / "Everybody Is a Star", released in December 1969. "Thank You" reached the top of the Billboard Hot 100 in February 1970.  In 1970, Sly Stone spent most of his waking hours on drugs. He became erratic and moody, and missed nearly a third of the band's concerts that year. The band did close out the Strawberry Fields Festival near Toronto, Ontario in August but live appearances on television talk shows such as The Mike Douglas Show and The Dick Cavett Show went unpredictably. Meanwhile, Sly hired his streetwise cohorts, Hamp "Bubba" Banks and J.B. Brown, as his personal managers; they in turn brought in gangsters such as Edward "Eddie Chin" Elliott and Mafioso J.R. Valtrano to be Sly's bodyguards. Sly enlisted these individuals to handle his business dealings, to retrieve drugs, and to protect him from those he considered his enemies, some of whom were his own bandmates and staff. A rift developed between Sly and the rest of the band; in early 1971, drummer Errico became the first to leave the band for other ventures. He was replaced with a succession of drummers until Sly settled on Gerry Gibson, who only remained with the band for a year before being replaced by Andy Newmark in 1973.  To appease fan demand for new songs, Epic began re-releasing material. A Whole New Thing was reissued with a new cover, and several of the Family Stone's most popular recordings were packaged into the band's first Greatest Hits album. Greatest Hits reached number two on the Billboard 200 in 1970.  During this period, Sly Stone negotiated a production deal with Atlantic Records, resulting in his own imprint, Stone Flower Productions. Stone Flower released four singles, including one by R&B artist Joe Hicks, one by a group called 6IX, and two pop Top 40/R&B Top 10 singles by Little Sister: "You're the One" and "Somebody's Watching You", a cover of a song from Stand!. For unclear reasons, Sly gradually withdrew his attention from Stone Flower, and the label was closed in 1971. Little Sister's "Somebody's Watching You" is the first popular recording to feature the use of a drum machine for its rhythm track.
what were the internal problems?
A: there was friction in particular between the Stone brothers and Larry Graham.

Some context: Krishnan Nair (25 July 1939 - 16 November 1980), better known by his stage name Jayan, was an Indian film actor, naval officer, stunt performer and cultural icon of the 1970s. He starred in over 120 Malayalam films. During his film career, he was primarily an action star and was particularly famous for his macho image and unique style. He was reputed for his chauvinistic appeal and well known for performing stunts of a dangerous nature on his own.
In the late 1990s and early 21st century, there was a resurgence of Jayan's screen persona in Kerala and his old movie scenes came to prominence again. It was owed mostly to programs by popular mimicry stage artists in the State, whose imitations of the star's mannerisms caught on and soon became commonplace in college stage events, television programs and mimicry stage shows along with quotes of superhuman strength known as Jayan quotes. However, it has been pointed out that many grotesquely imitated screen dialogues of Jayan are not actually his, but that of dubbing artist Aleppey Ashraf, who dubbed for many of his characters after his death.  The "comeback" of Jayan and his renewed popularity lately may be taken as an affirmation that Jayan has not been replaced even nearly three decades after his death. Today, Jayan is best remembered as the first and best action star of Malayalam cinema, so far, besides his trademark colourful attire, risky stunts, machismo mannerisms and unique speaking style. He has rightly won immortality in the hearts of the Malayalam film fans as a martyr in his yearning to thrill and entertain them even by putting his life at stake. Madhu, a famous actor prominent in the 1960s, once stated in an interview: "Jayan will forever be young and alive. No one can ever visualise him as an old man."  A film titled Avatharam presently under production, is attempting to bring back his screen persona using advanced technologies. A documentary on Jayan's life and death Jayan - The Man behind the Legend is nearing completion for release in the near future.
