Can anyone ID this plant please?

From a trip to Porto at beginning of the month.  Large 3-4m, slightly hairy, flower is sort of solanum like and its name is somewhere hiding in my head.  Can you help?
thanks

Looks like Solanum mauritianum.

Brilliant! Thanks.  I just hope for Porto’s sake that it was a cultivated variety that isn’t an invasive monster as we saw quite a lot of them...

I've seen it growing a lot in Goa and in The Gambia.

It is pretty...
