Raak] Perhaps Darren is unaware of the last time Musical Mornington Chairs was played, back in the late 1970's, when it was played by some very enthusiatic Chelsea football supporters on there way back from another local London village derby.

As a result, this unfortunate event is usually glossed over and not normally discussed in polite company.

Eager as a salamander.

[Darren] I thought you were obliquely referring to/associating it with Humph as a 'musical chair[man]' of MC.
