The Western Brothers (Hello Cads!) were actually cousins and they will be well known to anyone who is old enough to remember radio in the 1940's, appearing all the time on shows like "Workers Playtime", "Monday Night at Eight" and "Henry Hall's Guest Night". They both wore evening dress and monocles and sang in unison to George's piano accompaniment with a very laid-back, sophisticated air. With the demise of the variety theatres and the rise of television in the 1950's they broke up the act and one of them finished up running a confectionery and tobacco kiosk on a London (Euston?) Station. I think they both died in the 1960's.
