Question: Stardust starred an English musician who attained how many Top 40 singles in the UK? 
Context: Opus is the sixth studio album by Austrian pop rock band Opus.  It was released in 1987.  It peaked at #7 on the Ö3 Austria Top 40 Longplay.  The first single "Whiteland", peaked at #3 on the Ö3 Austria Top 40 Singles and #2 on the Ö3-Hitparade.  The second single, "Faster and Faster", peaked at #12 on the Ö3 Austria Top 40 Singles and #2 on the Ö3-Hitparade.  The third single, "Will You Ever Know Me", peaked at #24 on the Ö3-Hitparade. The Kinks were active for more than 30 years between 1964 and 1996, releasing 28 regular albums in the UK (24 studio, four live), and 30 in the USA (24 studio, four live, two compilation), where the early albums were slightly different from the British albums partly due to the method that publishing royalties were calculated in the two countries, partly due to difference in popularity of the extended play format (the UK market liked it, the US market didn't, so US albums had the EP releases bundled onto them), and partly due to the US albums including the hit singles, and the UK albums not; after "The Kink Kontroversy" in 1965 the albums were the same.  There have been somewhere between 100 and 200 compilation albums released worldwide.  Their hit singles included three UK number-one singles, starting in 1964 with "You Really Got Me"; plus 18 Top 40 singles in the 1960s alone and further Top 40 hits in the 1970s and 1980s.
