De Paul was the last established and well-known international artist to enter the contest for the UK, until Scott Fitzgerald in 1988, and she was the first British entry to write and perform her own song. "Rock Bottom" charted in several European countries, topping the charts in Switzerland, no. 2 in Austria, no. 4 in Germany, no. 4 in Portugal, no. 6 in Sweden (no. 4 on the Poporama chart), no. 7 in Ireland and Norway, no.8 in Belgium and no. 10 in France and Israel.
