The lead single "The Flyer" fared well in Canada and also became their final U.S. hit, peaking at No. 79 on Billboard in November 1983. The follow-up single entitled "Scratching the Surface" became popular in Canada, peaking at No. 45 in April 1984. Their sixth album, "Behaviour", was released in 1985 and included the singles, "Listen to Your Heart" and "What Do I Know?" (charted No. 57 in Canada). In 1986, Steve Negus and Jim Gilmour left the band over management concerns, soon deciding to form a new band project under the name "Gilmour-Negus Project" (GNP). In 1988, they released their one and only album, "Safety Zone" (featuring Robert Bevan on lead vocals). Meanwhile, Saga continued to record and tour, with Michael Sadler and the Crichton brothers augmented by session musicians. Their 1987 release "Wildest Dreams" enjoyed better distribution under new label, Atlantic Records, but it failed to match expectations in America. The lead single "Only Time Will Tell" became a popular chart favourite in Canada (No. 93), with a memorable video rotated on MTV for a brief period. However, the remainder of the album suffered from over-reliance on technology, with armies of sequencers and drum machines replacing much of the band's earlier trademark sound with Gilmour and Negus. For 1989's "The Beginner's Guide to Throwing Shapes", Saga refocused on their earlier European popularity which marked a return to their earlier progressive style with a few sci-fi orientated pop elements to it. In 1992, Steve Negus and Jim Gilmour returned to Saga. The band's next album, "The Security of Illusion", was well received by Saga fans in Canada and Europe. The 1994 followup, "Steel Umbrellas", was considered uneven when compared to their previous release, perhaps due to the material originally being produced for the short-lived television series "Cobra". However, despite lackluster album sales, Saga's 1993 and 1994 tours helped maintain some of the band's early popularity; their reputation as live performers was not lost among the band's long time fans. In 1995, Jim Crichton composed and produced the majority of Saga's next album, the conceptual "Generation 13". Inspired by a popular political treatise by the same name, the story follows main character Jeremy's troubled search for his real father. The concept is somewhat reminiscent of the storyline in The Who's "Quadrophenia".
