I stumbled upon this quite by accident. This was an album released many years ago, but which failed to make an impression at the time. It is made up of songs written my the Monty Python duo, Michael Palin and Terry Jones. Not the usual 'python' style, a bit more like Jake Thackray.
Anyway, here it is :- Barry Booth and his orchestra - Diversions.
