Wilf Pine was an English music manager, record producer and gangster. After a difficult childhood, he was sent to an approved school in Northumberland. This was followed by a brief spell as an enforcer and hired muscle on the Isle of Wight and in London, and as an assistant to British music promoter Don Arden. He then co-managed Black Sabbath for 13 months in the early 1970s, and also managed The Groundhogs, the Edgar Broughton Band and Stray, among others. Despite developing a close relationship with Genovese crime family capo Joe Pagano, carrying out jobs for the New York Mafia in both the US and the UK, and being an intimate of the Kray twins and numerous other British underworld figures, he never spent time in prison.
