This team in blue and white, who are a goal up (it should be two) and knocking the ball about nicely? They any relation to the St Johnstone team who've lost seven of their last nine and not won a game since the end of November?

Hibs captain Martin Boyle bagged the first goal of the day...

We'll try and clip as many of the goals as we can, so you can scroll back across the afternoon to see them.

Rudi Molotnikov is eager for a goal, coming close once more by firing low and wide after advancing into the the Bankies box.

It is one-way traffic at Easter Road right now.

Ross County are the first to go close as James Brown's cross drifts onto the top of the cross bar and goes over. Jerome Prior, the Livi keeper, looked a little worried about that.

Another chance for Elgin as a cross reaches Ryan Sargent unmarked at the back post, but the striker's header is poor and the Dons clear.

Danger signs for the visitors, who will be keen to avoid another Darvel experience.

A small cluster of Montrose fans are making some noise albeit slightly outnumbered in Glasgow's Southside.

A long journey back for those travelling supporters but a win for Scotland's League One side would make it all the sweeter.

Though Callum Davidson more than many, knows what it takes to get over the line at the national stadium.

Nearly a quickfire double at Easter Road.

The visitors are caught out at the back, allowing Martin Boyle to find Rudi Molotnikov, though the youngster blazes well over.

So close to an opener - and it's for the hosts.

Aberdeen struggle to clear inside their own penalty box, it falls to Dajon Golding and, although the striker delays his shot, his low drive from a difficult angle is cleared off the line.

It falls to another Elgin boot, but midfielder Lewis Hyde fires low and wide from the edge of the penalty box.

Clydebank walk out at Easter Road to a tremendous reception from their 2,500 support. Dreams of a place in the last 16. Can they achieve the win that many think is impossible?

The Motherwell fans are here in good numbers, somewhere close to 2,000. They're making a right racket as they literally and figuratively beat the drum for their side. Sadly, they've also brought pyrotechnics with them, and they're letting them off. Not a good look, smoke now billowing from the away end.

The Scottish FA run this tournament, so sanctions could well follow.

And we're up and running.

No VAR at any of these games by the way.

Before every Scottish Cup game today there will be a minute's applause for the great Denis Law, who passed away yesterday.

Scotland's joint record-scorer, the only Scottish player to win the Ballon d'Or prize, Manchester United icon.

A legend of the game.

A bouncing Burgh support have travelled through to cheer on Musselburgh Athletic in their first Scottish Cup fourth round game.

It's been a cracking journey so far for Liam Burns' sixth-tier side, and they're in search of a big auld scalp at Hamilton Accies.

The biggest game in their history, could it go down in Scottish football history?
