The humour of those two words has been lost on me long ago.

Those very words, although not appearing in any legislation, have been used to support my council's policy. The Local Government Ombudsman has also been convinced that these words have some legal relevance.

They have been used in an attempt to destroy the relevance of the only case law that concerns unpaid music making by pub customers, the 1899 one quoted above by the DCMS.

Where again they use the word 'impromptu' when the activity in Brearley -v- Moreley 1899 was a regular event.
