Elton John cracked the Top 40 as a duet partner to country newcomer Catherine Britt in 2005. The song was called 'Where We Both Say Goodbye,' a piano-driven ballad written by Britt and Jerry Salley. It was slated to appear on an album for RCA Records, but that never happened. Despite a slot opening for Brooks and Dunn, Britt would only score one more Top 40 single before being dropped and moving back to Australia.

In the mid-to-late '00s, there were a number of Australian stars who came to Nashville hoping to find fame with American fans. The McClymonts are an all-sister trio that have released several singles, and Adam Brand is a superstar in Australia who released 'Ready for Love' to U.S. country radio in 2010. It didn't crack the Top 40 and subsequent singles never materialized.

Thus far, Keith Urban and Sherrie Austin ('Streets of Heaven') are amongst the few singers from Down Under to find success in America.
