The band also released "Rock n' Roll Nights" in March 1979. It was the first BTO album to prominently feature outside songwriters, particularly Prism's Jim Vallance, who also co-produced the album. Vallance had taken over as main producer after Barry Mraz was fired by the band, and would later score huge success in the 80s with Bryan Adams. But like its predecessor, "Rock n' Roll Nights" also sold poorly (an estimated 350,000 copies worldwide). The album did, however, produce a moderately successful single called "Heartaches". Written by Turner, it cracked the Top 40 in Canada and reached number 60 on the US charts, making it the first BTO single in three years to chart in the US. BTO played this song on American Bandstand in February 1979 (with producer Vallance guesting on piano), along with another single from the same album called "Jamaica". Fred Turner and Jim Clench also appeared on "Bryan Adams debut album in 1980 as session musicians. (Adams had likewise contributed one song, "Wastin' Time", for BTO for the "Rock n' Roll Nights" album).
