Morris recorded a duet with INXS lead singer, Michael Hutchence, on a cover of Nancy Sinatra and Lee Hazlewood's hit "Jackson", it was included as a bonus track on the April 1984 (cassette only) INXS EP, "Dekadance", which reached number two on the charts. Morris and INXS performed "Jackson" live at the 1984 "Countdown" Music and Video Awards held on 19 May 1985. At Murphy's suggestion she teamed with INXS as a backing singer on their 1985 Australian tour—originally just for a few weeks—and stayed on for eighteen months on their 1985–1986 Listen Like Thieves World Tour. Morris recorded and, in November 1985, released her first single for Warner Entertainment Australia (WEA), "Get Some Humour", with a contribution from Dave Dobbyn, which reached the top 100.
