The Western Brothers were an English music hall and radio act, who were popular from the 1930s to the late 1950s, performing self-written topical songs which often lampooned the upper classes.
In October 1948 they became involved in a controversy because of a joke that Kenneth told between songs during a live performance on the BBC Home Service.
In reply the Brothers received a letter from the Solicitor-General: Mr Gaitskell is happy to accept your assurance that no personal reflection was ever intended.
However, for Mr Gaitskell, and I hope for you, the matter is now at an end.There was no lasting impact on their career and they continued to appear on both radio and TV throughout the following decade.
[2] A BBC Radio 4 programme describing their career was broadcast on 22 November 2012 entitled Mockery with Monocles: The Western Brothers Revealed.
