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 and an occasional lead on album cuts (Jay sang lead on some of the harder-edged songs, two of which were released as singles), but Donny largely switched to instrumental contributions for much of 1972 to accommodate his voice change; by 1973, the change was largely complete, as Donny had settled from his former boy soprano range into a smooth baritenor voice. With their clean-cut image, talent, and energetic pop-rock sound, the Osmonds toured to crowds of screaming fans in the US. They even had their own 19721973 Saturday-morning cartoon series, The Osmonds, on ABC-TV. By this time, the Osmonds had broken through in the UK as well: counting group and solo recordings, members of the Osmond family charted 13 singles on the UK charts in 1973. Some observers coined a new word, "Osmondmania", to describe the phenomenon, by analogy with the similar "Beatlemania" of the previous decade. Donny's voice change was a major upset to the group's formula that had proved so successful, mainly in that it eliminated Merrill's young-sounding co-lead's voice (forcing Merrill's already mature tenor voice to strain to cover most of the higher notes, with audible difficulty, through the next few years). The success of Crazy Horses singles "Hold Her Tight" (No. 14) and title track "Crazy Horses" (on which Donny did not sing, but did contribute with a prominent synthesizer riff) kept the group very popular through 1973. As the group toured, Donny continued to sing his solo hits, with the band progressively lowering the key until his voice change was complete. Emergence as teen balladeers: The Plan and Love Me for a Reason The older male Osmonds were of age to go on church missions, yet they believed they could reach more people through their music. They recorded an ambitious album in 1973 called The Plan, perhaps best described as a Mormon concept album with progressive rock aspirations. One reviewer suggested that The Plan carried a too-strong religious messageMormonism is, after all, fairly conservative and not usually associated with the
