I am Jack Kingston’s youngest son and owner of all of his music as published under Wentworth Music, Socan/BMI Canada. His music is very much alive and periodically I am contacted by someone wishing to re-record something. Most recently, CNR Special was recorded by the Good Brothers. I receive royalties on his writings to this day. Sometimes, I even perform his music and have covered quite a few of his songs on two different CDs that I released. You can even find his music still available on eBay as part of a cd release compilation or even used old vinyl records. Amazing to see it there being the last release of his was some 45 years ago around 1970!
