to get significant airplay on radio stations, a few months after the album's release. Extensive touring with Fleetwood Mac, Heart, and the Doobie Brothers, in addition to major headlining shows, cemented Ambrosia's reputation as a live act. For the 1978 touring band, North returned and the group added a second keyboardist, David C. Lewis, as well as an additional singer, Royce Jones, who joined in late 1978. In April 1980 Warner Bros. released One Eighty, which produced two of the year's biggest hits. The first, "Biggest Part of Me", reached number three for three weeks on the Billboard Hot 100, and crossed over to the soul chart, where it peaked at number thirty-five. The second, another blue-eyed soul hit, "You're the Only Woman (You & I)", reached No. 13 on the Billboard Hot 100. One Eighty earned the band three Grammy nominations, including Best Pop Vocal Group. A headlining world tour followed. For the Japanese leg of the tour, the group was joined by their longtime friend Cliff Woolley (formerly of the Association, who had also guested on Life Beyond L.A.) on guitar, harmonica, and backup vocals. The title of the album One Eighty was believed by fans to signal the group's "180-degree" change in direction. The band maintains that the album title came from the fact that they began recording in January 1980 (1/80). Also in 1980, the band contributed the song "Outside" to the film Inside Moves, and "Feels So Good to Win" appeared in the film Coast to Coast later that same year. The following year they placed another track, "Poor Rich Boy" (written by Burt Bacharach), on the soundtrack of the film, Arthur. In 1982, David C. Lewis briefly left the touring group to be replaced by Bruce Hornsby, four years before his own rise to stardom. The same year, Ambrosia released their fifth and final studio album, Road Island (May 1982), their first effort without the assistance of Freddie Piro's production company. Produced by James Guthrie, the album consisted of intense, driving hard rock (outside of the soft ballad "Feeling Alive Again" and the progressive rock closer "Endings"). Though it received some airplay with "How Can You Love Me", the album was a commercial disappointment. The band broke up afterwards, ending their run of chart success. Later years After Ambrosia, David Pack pursued a solo career and produced or worked with many top artists. Pack's
