Galeries Victoria couple

I've seen this couple often, over many years, around Sydney - & this is one of their favoured haunts it would seem. They're always smartly dressed and always come across as very proficient musically - mixing it up with styles and instruments - piano accordion & others . While they have a generally upbeat demeanour they're not the most animated of street performers. But how long could you keep up 'razmatazz' anyway? I'm impressed they've stayed together as a couple for years - can't be an easy way to bring home the bacon but their attitude suggests they're stayers.
