What could be more appropriate when £1,000 has sailed up the Swanee River than a rendition of Swanee Kazoo. If that is too highbrow for you then here is the score for Commonwealth as purchased by Barnet Council with your money.
Score of Commonwealth
The copyright belongs to Barnet Council so play it all you like if you are a Barnet resident and get your money's worth. You may need to get a few friends round and once the bagpipes start the noise abatement officer will appear - once he/she realises the royal connection, yes Brian Coleman was instrumental in the selection of Tim Benjamin, the composer, the noise abatement officer will sing along.
Yours frugally
Mr Mustard
