His pleasant rolling bass-baritone voice made him a regular presence on the stage and in films for more than fifty years.

A decade later he reprised the role for a performance of Treasure Island at the Mermaid Theatre in the winter of 1961–62, where the cast included Spike Milligan as Ben Gunn.

Impressed with the writing of English playwright John Antrobus, he introduced him to Spike Milligan, which led to the production of the one-act play The Bed Sitting Room.

It was later expanded and staged by Miles at Mermaid Theatre on 31 January 1963, with critical and commercial success.

[5][6][7] Miles was also known for his comic monologues, often delivered with a rural dialect, which were issued on record albums.
