I found the email from MONA - from 2015 !
It goes to https://theo.artpro.net.au/login/
and after entering my email I got sent a fresh link and can see my tour again.
Shall I say that again?
2015
At my work, the IT people can't ever manage any web system change without breaking every link, over and over again for as long as we've had web systems.
(I've been there 35 years so that's only part of my time.)
So a tip o' the hat to MONA for this one!
