Franz Ferdinand frontman Alex Kapranos is less than impressed by the British royal family's enthusiasm for his music, as he insists royals and rock doesn't mix.

Second-in-line heir to the throne Prince William reportedly loves the TAKE ME OUT hitmakers, but the Scottish stars are keeping their distance from dignitaries.

He says, "The royals have nothing to do with music.

"Somebody told me that Prince William is a fan, which is great, but I don't think the royal family or politicians and musicians should mix."
