A video of cousins Gav and Tom Douglas, otherwise known as Jazzy Gav and Sugar Dougie went viral on On The Tools, a Facebook community for construction workers.
Now the pair are in battle with MC Builder from the south, who is giving them a run for their money.
The Rapping Deccys spoke on The Star’s Steel City Sofa series at The Grapes pub.
Gav said: “We wrote a little tongue and cheek rap on our lunch break about our job.
“We filmed it and sent it to On The Tools who really liked it.”
Tom said: “On the Tools posted our video and asked if anyone would like to battle us… we were just having a bit of fun.”
The video has now had millions of views.
Gav added: “MC Builder put a video out but little did he know the Rapping Deccys are not to be tested.
“We’ve got Glastonbury to think about this year and T in the Park obviously but we’re still making time to get back at MC Builder.”
