Rick Springfield (born Richard Lewis Springthorpe on 23 August 1949) is an Australian singer-songwriter, musician, and actor. A member of the pop rock group Zoot from 1969 to 1971, he had an initial career as a charismatic 'teen idol'; he started his string of solo works with a debut single, called "Speak to the Sky", that reached the top 10 in Australia. In mid-1972, he relocated to the U.S., evolving into a more strident power pop sound as the years passed. He had a #1 hit with "Jessie's Girl" in 1981 in both Australia and the U.S.
