Sing!, often stylized SING!, is an annual student-run musical production put on by some high schools in New York City. It is a theater competition between the various grades, with the setup between grades differing from school to school (such as sophomore-freshman vs. seniors vs. juniors, senior-sophomore vs. junior-freshman or freshman-senior vs. sophomore-junior).
Inter-Sings are Sing competitions held between different high schools. They have been held in Brooklyn, Queens, Staten Island and Long Island. Sheepshead Bay High School had a long string of victories in the three-school competition called InterSchool Sing (or Inter-Sing) during the 1970s and 1980s, punctuated by wins by Lincoln High School.
Inter-Sing first started on Staten Island in the late 1970s between Tottenville and Susan Wagner High Schools. More recently, Susan E. Wagner High School won the Staten Island competition in 2007 with their Junior production of "The JSV Circus"; Staten Island Technical High School won in 2008 with their Senior-Sophomore production entitled "Carnicus"; and Tottenville High School, which participated for the first time, won in 2009 with Senior Sing X's production of "Narneville", a twisted fairy tale.
