Question: Of the musical acts Vixen toured with, which one has been active the longest? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

Question: How old was the architect who designed part of the Marienlyst Castle when it was built? Passage:Hans van Steenwinckel, the royal architect, designed and built the original pavilion and parterre garden in 1587, for King Frederick II of Denmark. The royal estate was then purchased in 1758 by Count Adam Gottlob Moltke, who completely changed the original pavilion and garden with the help of French architect Nicolas-Henri Jardin between 1759 and 1763. The additions led to its present-day architectural structure and façade. Jardin also redesigned the original parterre gardens, changing them to a larger, more modern garden à la française design, with symmetrical hedges, avenues, fountains and mirror ponds. Within the castle wall boundaries, these elegant garden grounds remain to a large extent intact, but outside, much of the garden has been lost, including the most renowned romantic landscape garden in Denmark, designed by Johan Ludvig Mansa in the 1790s. This was mostly due to the sale of much of the original property by the Helsingør municipality which had purchased the entire Marienlyst estate at auction in 1851. One of the lot purchasers was J.S. Nathanson, who in 1859 built Hotel Marienlyst, the first luxury hotel in Helsingør, named after the castle.
