BTO completed the "Rock n' Roll Nights" tour in late 1979, and officially disbanded in early 1980. After Randy recorded the solo album "Survivor" in 1978, he went on to form the short-lived Ironhorse in 1979. Ironhorse released two albums, "Ironhorse" and "Everything Is Grey", before disbanding. Tom Sparks was the vocalist for the first Ironhorse album, along with Randy, but was replaced by Frank Ludwig for the second album in 1980. Sparks reportedly did not like the constant touring and being away from home for such long amounts of time. A reformed version of Ironhorse, renamed as "Union", released one album in 1981 entitled "On Strike". Fred Turner was a member of Union along with Randy Bachman.
