Opposing campaigns in the Scottish independence referendum appear to have chosen the same Big Country song One Great Thing to launch their campaigns.

A spokesperson for Yes Scotland, which is urging Scots to vote for independence in the forthcoming referendum, said: "With an agreement in place, artists commissioned by Yes Scotland recorded a cover version."

However, a spokesman for the Better Together campaign said "it is categorically not the same tune" as One great Thing.

He added that it was a new track called Down Under by Scottish DJ/Producer Munroso which "neither samples, nor uses, nor is inspired by Big Country."

Here is a a sample of the two tunes together.
