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