I was fortunate to be a friend of both Nigel Denver and Karl Denver (Gus McKenzie).
I produced and arranged a few LPs for Nigel and also released an LP called The Karl Denver Trio on my NEVIS label in 1978. It featured Karl, Gerry Cottrell and Kevin Neill who had a solo hit with his guitar version of The Harry Lime theme in 1974.
Karl/Gus was a regular visited to my home in North London. When I was first introduced to him in the mid 1970s we spoke in Norwegian. We had both been merchant Navy sailors, he in the Norwegian and I in the Swedish and I pretended to be a Norwegian seaman…..but only for a few minutes!
He told me a funny story how he was arrested in South Africa. He could “throw” his voice and in a bar he pretended to speak into his watch which replied in a small high pitched voice. The South African cops arrested him so they could examine his watch. They considered it some kind of spying device!
