Woow...Now that's a surprise...I really wasn't expecting that...I mean, as for myself, when Blackout was first released, Radar was one of my top three favourite songs on the album but when Circus came out, Radar was waaay back after songs like Out from under, Kill the lights, Unusual you, Shattered glass that could have been waay more proper singles...
It doesn't matter that Radar had a small amount of succes when it had that limited release...People liked the song back then, now it's kinda overpassed & her new material suits better with the whole circus theme...I honestly, from the beggining didn't consider putting Radar on the Circus album a good idea...it's too Blackout
And i would've strongly recommended a ballad-single, after all, all 4 ballads are potentially strong singles, although i doubt Blur ...
Hope though Radar will pull it through & will help Blackout reach at least the 1 million sales mark in the US for a Platinum certification...Love Brit
