Do you know anyone who has changed a letter ???

[ON THE ROAD]

* Which act's name has changed by one letter in the five years between their only two top ten UK hits *
Knowing this quiz, it could be either albums or singles charts, and it may mean, dropped a letter or swopped a letter i.e the Rezillos/Revillos or Liberty X / Liberty
I have done the full A-Z of the Guinness books of hit singles and albums and the Virgin and NME equivalents, and not found the answer. I have found a few name changes and several chart histories that consist of only two top ten hits, but not for the same act. This question is driving me mad, so does anyone out there know of any acts who have slightly altered their name that I have missed Many Thanks
