This thread has been round the bring, brang, brung loop several times.
It is now in danger of wandering off into a general discussion on various atypical usages. That would be absolutely dreadful, so I have closed the thread.
I think an intelligent reader will be able to glean from the thread, as it stands, a useful perspective on bring, brang, brung.
So, with thanks to MrMagoo, who first bringed this topic to our attention, AlonYo who dugged it up in March last year, and brad243, who brunged it to the fore this time, I think it's time to put it away for a while.
Future generations wishing to resurrect the topic are welcome to propose so to the moderators of the time.
