I may be way off on this... but I seem to remember some sort of hubub in the 70's (?) and some sort of announcement, followed by the usual *tsk tsk* and *oh my* of the audience.
Nothing was ever really spoken about WHAT he did - just that he had been DFed - or replaced - or whatever.
It made me wonder 'what the heck?' - but the 'penalty' for questioning ... well... anyway.
I do not ever remember anything in print - other than the 'letter' if it was even in one... and the announcement from the platform.
Regards,
