IN: The Osmonds are an American family music group with a long and varied career. The Osmond Brothers began as a barbershop quartet consisting of brothers Alan, Wayne, Merrill and Jay Osmond. They were later joined by younger siblings Donny and Jimmy, both of whom enjoyed success as solo artists as well. With the addition of Donny, the group became known as The Osmonds, and enjoyed its greatest success as both a boy band and a hard rock ensemble.

Record producer Mike Curb saw the Osmonds perform as a band and recognized that they combined a rare mix of polished performing style, instrumental skill, and vocal talent. He helped the Osmonds get a record contract with MGM and arranged for them to record at Muscle Shoals with R&B producer Rick Hall. Under Hall's guidance, the Osmonds hit the top spot on the pop chart with "One Bad Apple" in 1971. The song, "One Bad Apple", written by George Jackson, who had The Jackson Five in mind when he wrote it, was originally presented to Motown Record's Chairman of the Board, Berry Gordy, for The Jackson Five to record, but he turned it down. It was then presented to MGM Records for The Osmonds; both the Jackson Five (who were admittedly inspired by The Osmonds' early success) and the Osmonds were aiming for the same Bubblegum sound and style of music, and it became their first number-one hit single, released on November 14, 1970. The Osmonds soon had hits with other light, R&B-style pop numbers like "Double Lovin'" (#14) and "Yo-Yo" (#3). In each of these hits, the formula was the same; Merrill sang lead, and Donny was "co-lead" in essence, singing the "hook" or "chorus" of the song. At this time the Osmonds also recorded several hits that were billed to Donny, the lead soloist on the songs: "Sweet and Innocent" (#7), "Go Away Little Girl" (#1), "I Knew You When" (#9) and "Puppy Love" (#2). The Osmonds were at their peak of popularity. The Osmonds began writing and performing their own music and their sound moved towards rock music beginning with their album Phase III. In addition to "Yo-Yo", Phase III produced the major hit "Down by the Lazy River" (#4). The following Crazy Horses album was the band's first really personal statement -- the brothers have been quoted as saying that the title song refers to air pollution from cars, and its instrumentation featured an even harder rock sound bordering on early heavy metal. They wrote all the songs and played all the instruments with Alan on rhythm guitar, Wayne on lead guitar, Merrill on lead vocals and bass, Jay on drums and Donny on keyboards. All the brothers sang backing vocals, with Jay and Donny sometimes singing lead parts. But Donny singing co-lead on these songs was abandoned for the reason given below (except for Lazy River, which he also did not sing co-lead on).

Did they collaborate with any other artists?
