on his second album, he collaborated with sandy simpson to record "through the door" (1982), which took up the theme of spiritual quest inspired by the novels of george macdonald ("the golden key"). it also continued the use of synthesizers in the slightly sci-fi themed song, "the jupiter effect". it was also on this album that johnson first recorded his personal 'theme' - 'someday someday' — a song he would record in several versions throughout his discography.
