Duncan's string of top-10 hits continued into 1979 – most notably a cover of Johnny Rivers' "Swayin' to the Music" (released by Duncan as "Slow Dancing") and "The Lady in the Blue Mercedes" – and he even enjoyed another top-20 hit with Fricke in 1980 with a duet version of Michael Jackson's "She's Out of My Life". His star power faded in the early 1980s with changing musical tastes, although his biggest songs were popular on country radio through the late 1980s and early 1990s.
