Does this mean, therefore, that the songs of Tom Bliss should not be sung alongside traditional songs, because it robs them of their uniqueness?

Why does that not apply to songs by MacColl, Tawney and McGinn?

Does this also mean that all four of these artists were wrong to sing traditional songs alongside their own compositions?
