A well-known half Iranian, half Scottish singer changed his surname in Britain from Danesh to Campbell, much to the displeasure of his dad. Campbell is the maiden name of Dariusí mother, Avril. Dariusí retired doctor dad, Booth, 67, released a statement to The Sun from the family home in Glasgow. An unnamed insider told The Sun that the Dariusí name change was a smart showbiz move. ìHollywood has gone Scots crazy now that Gerard Butler is a big box office draw.î The source added, ìCampbell definitely sounds a lot more Scottish, which will do Darius a world of good out there.î In the British pop song world, Darius is mainly known by his first name.
