Andy Classen (Sabina's ex-husband - and not her brother, like some sources claim - and Holy Moses' guitarist from 1981 to 1994) is still the band's main songwriter and producer. Before Sabina married Andy in 1983 she was known by her maidenname Hirtz. Her (real) brother Tom was in Holy Moses too for a short time, he replaced Sabina for four weeks as vocalist in 1984.
