"A new record deal with PRT was signed and a new single put out "Edge of a broken heart" was the bands first hit, No 1 in the national rock charts, ahead of the likes of Def Leppard & Whitesnake, the song eventually reached only lower reaches of top 50 in the national singles chart, owing to Gallup (chart organiser) banning it because Jonathan King had plugged it 2 weeks running in his "The Sun" national newspaper column."

Couldn't find anything related, does anybody know if this is true?
