Zil had also asked about what happened to Ken after his playing days. There is a fair bit about the fates of all those who played in the first League Cup Final in Adrian Booth's excellent book 'The First Finalists'. As of 2005 Ken was living in retirement in Anlaby at the west end of Hull. He still followed the fortunes of Hull FC and spoke to local football organisations about his days with the club. After playing for Hull then S****horpe he was player-manager at Scarbrough and then briefly played for Bridlington Town. He went back to Hull FC as full time Youth Coach and then had his spell there as club manager in the late 70s (at one point signing Trevor Phillips from the Millers.) After being sacked by Hull FC he retired from pro football in 1979 and worked for a freight forwarding company. He continued to play non league football.
Sorry I don't have anything after 2005.
