Born in Lansdale, Pennsylvania to an Italian-American family, March was discovered at age 13 singing at her cousin's wedding[2] and was introduced to record producers Hugo & Luigi.

[1] March became the youngest female artist with a number-one hit, at 15, in late April 1963, a record that still stands for the Billboard Hot 100.

[1] She won the Deutscher Schlager Contest in 1965 and her song "Mit 17 hat man noch Träume" ("At 17 you still have dreams") placed No.

March made another Eurovision attempt in 1975, when she performed the Ralph Siegel composition "Alles geht vorüber" in the German national contest.

[1] In 1984, however, Jermaine Jackson and Pia Zadora achieved a major European hit single with the track "When the Rain Begins to Fall",[7] co-written by March.

The cult film Hairspray featured "I Wish I Were a Princess" in 1988, and a retro fad in Germany brought her some continuing success starting in the mid-1990s with the album Die Freiheit Frau zu sein (1995).

March currently works largely in Germany and in the Las Vegas music scene and has also performed at Dick Clark's American Bandstand Theater in Branson, Missouri.

A collaboration with Scandinavian songwriter and producer Soren Jensen, the album Always and Forever was released on October 13, 2010.

It was followed by a special edition for the German-speaking countries in April 2012,[10] including two duets with the Dutch singer José Hoebee, one of them being a cover version of "I Will Follow Him"; which had also been a number-one single in the Netherlands and Belgium for Hoebee in 1982 (March further recorded a subsequent recording in 2012 for a 2013 release to commemorate the song's 50th anniversary).

March also recorded another version of "When the Rain Begins to Fall", as a duet with the German singer Andreas Zaron.
