Gooner, Malone, Chrise
TAGRAG I remembered from Shakespeare's 'Julius Caesar' Act 1 Scene 2 where Casca describes the 'tagrag people' clapping and hissing Caesar according to whether he pleased or displeased them.
In the clue the definition is just 'rabble' as 'threatening' refers only to the t and g.
Curiously Shakespeare uses it as an adjective but the crossword as a noun.
