During the spring of 1979, the band returned to the studio to record their third and what would be their most commercially successful album. Mitchell was now the principal songwriter and wrote/co-wrote four songs for the album. Although it was his largest contribution yet for a single album, it fell short of what was needed. In an effort to help, Vallance became involved again and brought along his new songwriting partner, Bryan Adams, to contribute to the songwriting effort. Adams, who at the time was an unsigned recording artist, wrote/co-wrote three songs. Vallance, meanwhile, co-wrote one track as Rodney Higgs, arranged two tracks using his real name, and played drums, bass and guitars on several tracks without credit.
