During the late 1960s, Glen Campbell began aiming his music at the mainstream pop charts, adding strings, horns and other pop music flourishes to such songs as "Wichita Lineman", "By the Time I Get to Phoenix", and "Galveston", which allowed his music to chart both in country and pop. While such artists as Lynn Anderson and Charlie Rich followed Campbell's example into the early 1970s, it was Dolly Parton and Kenny Rogers who, during the mid to late 1970s came to personify the concept of country pop crossover, with both artists maintaining a consistent presence on both the pop and country charts well into the mid-1980s, culminating in their duet, "Islands in the Stream", which topped the country and pop charts in 1983.
