Jo, we have a couple of email addresses from Spiro's business cards. Not sure if they are still current but maybe worth a try.
They are
CorfuArillasPortofino@hotmail.com
or
portfino@otenet.gr
(The last one was handwritten. Not sure if the o is missing from portfino.)
When we were there in Sept, Spiro was telling us about his gall bladder problems and his plans to go to America at the end of the season, so I don't know how quickly he will be able to respond.
hope this helps.
