A long shot but...

I have a piece of music in my head. It is an old recording of a tenor singing, possibly in a foreign language. One never can tell with these tenors. It is a grand piece of music, and quite a famous one I think. The tune goes something like: daa daa daa dee da-daa, daa daa daa DEE da-daa. And that's all I can remember. If anyone can get it, you a bloomin' genius and I love you for it.

Pavarotti singing Nessun Dorma? Large Italian bloke with lots of facial hair, it was the theme for a World Cup or European Cup or something in the early nineties

If it's quite soft and slow, it could be Santa Lucia?
