On The Dark Side by John Cafferty & the Beaver Brown Band. This was written for Eddie and the Cruisers, a 1983 movie about a New Jersey bar band. In the film, the song becomes the band's big hit and leads to a second album and a conflict with their record company. Kenny Vance was the music supervisor on Eddie and the Cruisers.

The diagnostic procedures available for prenatal diagnosis of Down syndrome are chorionic villus sampling (CVS) and amniocentesis. These procedures, which carry up to a 1% risk of causing a spontaneous termination (miscarriage), are practically 100% accurate in diagnosing Down syndrome. Amniocentesis is usually performed in the second trimester after 15 weeks of gestation, CVS in the first trimester between 9 and 11 weeks.
