As a history nut,
professional nostalgist (I am aware this is not actually a word) and vehement loather of the present-day, there are a million and one times and places in the past I would give my right arm to see.

London 1966
Seattle ‘64 to see The Sonics & The Wailers in their prime
Ancient Egypt, Greece, Rome etc.
Tudor London, Regency London, Victorian London….
Aztec/Inca/Mayan culture pre Spanish conquest

Fuck it, I’d take the mid 80s over this shit….

I did London in 1966
It was overrated.

So did I - don't remember it, natch.

Did you see Hendrix?
My Godmother did, when he was on one of those package tours with, I think, The Walker Brothers.

Would you be tempted to offer Top Tips, like,
'Don't look now' to King Harold, or 'Best set the timer' to King Alfred.
Or 'if you blow air through that molton pig iron the carbon will oxidise and generate a greater heat' to King James, who would probably top you.
