Their biggest hit, "Just an Illusion", peaked at number two in March 1982 ("Just an Illusion" would later be used as the end title song to the 1986 film, "F/X"), followed by "Music and Lights" (number five in June), "In the Heat of the Night" (number 22 in September, also the name of their second album), and "Changes" (number 31 in December). This was accompanied by a sell-out concert tour of Europe, with 22 dates in the UK. The trio frequently appeared on BBC Television's "Top of the Pops", and other pop music television programmes, with a distinctive exotic style, reminiscent of Roman senators, harem orderlies and slaves. John made a guest appearance on "Doctor Who" in 1983. They were also known for their esoteric album sleeve notes.
