Biffy Clyro's Simon Neil and James Johnston made the draw for the Scottish Cup this afternoon (January 11) - and drew bitter Glasgow rivals Celtic and Rangers against each other.
The Ayr rockers were drawing the ties for the fifth round of the cup, with the country's two top football clubs pulled out to face each other at Rangers' ground, Ibrox, over the weekend of February 5/6.

The Scottish duo aren't the only musicians to get involved with determining the fates of football clubs recently. Noel Gallagher and Serge Pizzorno of Kasabian drew the FA Cup third round last December.
