Many thanks are due to our resident musicmaccolligist Vic Smith for explaining to us the keys of U and R.

Here in Liverpool however, we have a long history of successfully assimilating ethnic groups from all over the world, with the result that we have some very interesting hybrid harmonies. EG:-

We combine the keys of Arrrrh And A, as in "Ahhhh eyyyy, the pub's shut. Wherwe gonna gerra bevy from now at dis time er night?"

Also it is common to find the keys of A and U combined, as in "Eh You. Gerroff me friggin' sarnies".
