He only scraped into the top 20 with 3 singles, yet due to the lack of talent around and the huge success of the Tommy Steele story they made a film vehicle for him.He then dodged the draft, got branded a coward " Special privileges for pop stars" then then became a drunk, got arrested etc etc.
Of all the rock revival shows I have seen Terry Dene was the best performer, he was about 53 then but looked much younger. He had a lot of success in Sweden.
