Spring Heeled Jack U.S.A. (more often known simply as Spring Heeled Jack) is a third wave ska band based out of New Haven, Connecticut. The band was formed by guitarist/vocalist Ron Ragona and drummer Dave Karcich in 1991. After a short breakup, Ragona and Karcich reformed the band with a new lineup. This lineup went on to record two albums before announcing a hiatus in 2000. While the band members moved on to perform in several new bands, their intention was to play the occasional reunion show.
