PROBLEM: Passage: Medieval Krakow was surrounded by a 1.9 mile (3km) defensive wall complete with 46 towers and seven main entrances leading through them. The fortifications around the Old Town were erected over the course of two centuries. The current architectural plan of Stare Miastothe 13th-century merchants' townwas drawn up following the Tatar invasions of 1259 and 1287. It features the centrally located Rynek Gowny, or Main Square, the largest medieval town square of any European city. There is a number of historic landmarks in its vicinity, such as St. Mary's Basilica (Koscio Mariacki), Church of St. Wojciech (St. Adalbert's), Church of St. Barbara, as well as other national treasures. At the center of the plaza, surrounded by kamienice (row houses) and noble residences, stands the Renaissance cloth hall Sukiennice (currently housing gift shops, restaurants and merchant stalls) with the National Gallery of Art upstairs. It is flanked by the Town Hall Tower (Wieza ratuszowa).

PROBLEM: Passage: The follow-up, Waterpistol, was recorded in 1991 at London's Star Street Studio and Chapel Studios, Lincolnshire. Shortly after the recording of Waterpistol was complete, the Star Street studio burnt down and most of the tapes were destroyed. The only remaining DAT of the album was in the possession of producer Chris Allison. At the time, Allison was in Los Angeles, and when he returned, it transpired that he had left the copy in his hire car. It was only found weeks later after a frenzied search. However, by this point, Ghetto had folded so the record was without a distributor. Shack split, with Wilkinson joining fellow Liverpudlian John Power (formerly of The La's) to form the successful Britpop band Cast. The Head brothers accompanied Love for a few touring dates in 1992.
Link Information: none Answer: none

SOLUTION: How many albums did John Power have writing credit on the year Waterpistol was recorded?
