My Mum used to play the piano in a pub. But that was back in the day when every pub had a piano. It should be mandatory nowadays, you shouldn't be able to call it a pub if it doesn't have a piano.

And what's this old Codswallop about electricity. It's been around long enough now to be traditional.

So take yer ol' Joanna along and plug it in and if they complain then that gives you the right to complain about every song that was written after electrical power came into use.
