I have combed thru the notebooks (unpub) rather carefully for that
period, and I believe I have read (and have copies of) every review
published in Australia and NZ, as well as all interviews but one.  He
did introduce new material into the programs downunder (like the
Australian poem), but such material is recorded in his notebook(s) as
well as by reviewers in newspapers.  Each program he gave was entitled
"MT At Home," and in the plural they were referred to as "At Homes". If
he had such a routine, it must have been introduced after he left the
antipodes.

If anyone turns up a routine called (or capable of being called) "At
Home", I would surely like to hear about it.
