Luxembourg hosted the contest for the 4th last time after Corinne Hermès' victory the year before.
After having held the contest last in 1973, Luxembourg played the host for the 1984 Eurovision Song Contest. The total number of participants was 19, one country less than in the preceding year as Greece decided not to enter a song. The contest also clashed with Israel's Remembrance Day, so the country wasn't present in Luxembourg either. Ireland returned to the contest though, finishing second. The Irish song was written by former Eurovision winner, Johnny Logan, under his real name Sean Sherrard. The song Terminal 3 was performed by Linda Martin, who later returned to win the Eurovision Song Contest in 1992.
