He said that he did not feel more vulnerable when performing music compared to acting.
“They’re two very different things. When you’re acting you need to go down a rabbit hole, a separate, alternative reality, a parallel world,” he said.
“You need to sublimate yourself to the journey, to the script and the story. You’re an interpreter.”
But he said that writing and performing his own songs made him “author and also interpreter”.
“It’s a different kind of psychological journey that you take,” he added.
“It’s not immersive in the sense that you become something else.”
Of his television career, Lewis said that he had been “very lucky” and “completely unwittingly” at the vanguard of a shift in TV, in shows which enjoyed global success.
“I’ve been very fortunate and I’ve loved doing all of them,” he added.
His tour in the autumn includes performances in Edinburgh, Glasgow, London and Brighton, where he played a set on 10 June at record shop Resident.
