While the Concertina siblings are indeed triplets, Sissy, through pure will on the part of his mother, wasn’t born until a few years after his sisters, making him the youngest of the Concertinas. His older sisters, thrilled with their new toy, developed a penchant for dressing him in the cast-off clothes of the Concertina family serving girl, Meredith. As a result, no one knew the true sex of the child until the whole can of worms was unleashed one drunken evening by none other than Christina Onassis when she seduced the young Concertina aboard one of her father's yachts. In an ironic twist, the despondent Sissy found solace by joining the Vienna Boys' Choir just after his sister's unfortunate incarceration. Sissy too was asked to leave the Boys, for a whole different set of reasons. Unwittingly, it was because of Sissy's recklessness that the Sisters found themselves pursuing a career in show business. When he turned 21, his father turned over the family business to him. The great grandfather of the musical trio, Dauphin Concertina Sr. II was the inventor of plaster of paris. Through a typographical error, young Sissy mistakenly thought he'd been charged with the business of getting plastered IN Paris and squandered the entire fortune in 11 and 3/4 weeks, leaving the sisters no choice but to do SOMETHING for a living.
