Johnny Oro -1966

Hello to all.
In huge need of help so hoping somebody may be able to give me some leads.
We are looking to locate Franco DeRosa who played Juanito Perez for a cast reunion event in September.
All i have really found out is that after acting in various programmes in the UK during 70s and early 80s he returned home to italy.
A guy at StudioCanal told me he recalls seeing him in an interview a few years back but i haven’t managed to find reference to it.
If anyone has some information i would be most grateful and there will certainly be some beer vouchers sent your way!
Best wishes
