I left on the final whistle and fans were already hanging around outside the Milburn Stand reception singing the same song.
The sale of Yohan Cabaye, without replacing him, was at the heart of the trouble ... but Sunderland's thrashing of the mighty Magpies (with ease) produced another home defeat Alan Pardew could well do without.
The Cabaye song "you're gonna have a riot on your hands" just about came true.

Angry scenes flared as Newcastle United fans squared up to police after leaving St James Park following their team's 3-0 defeat.
A wall of police officers, mounted and on foot, was formed on St James' Boulevard after full time while SAFC fans were kept inside.

There were loud bangs as flares were thrown into the air and towards police, startling the horses.
Police dog handlers put on riot helmets and walked towards them.
The fans were forced back by police before Sunderland fans were escorted out of the ground.
Several Newcastle United fans waited to watch their rivals leave.
The Black Cats supporters taunted them singing loudly. Some beer bottles were thrown.
At around 3.45pm a gang of youths gathered surged down Pudding Chare, off the Bigg Market. They began emptying a skip and throwing rubbish towards officers.
Northumbria Police have since said that they do not believe those involved in the Bigg Market disturbance were at the match.
