The 84-year-old celebrity is charged with 12 counts of indecent assault on four victims aged 19 or under between 1968 and 1986. Harris denies the charges.
Opening Harris's trial Friday, prosecutor Sasha Wass said the victims ''were overawed at meeting Rolf Harris. Mr. Harris was too famous, too powerful and his reputation made him untouchable.''
Australian-born Harris has been a British broadcasting stalwart for decades, and had musical hits with ''Tie Me Kangaroo Down, Sport'' and ''Two Little Boys.''
He is one of several veteran entertainers to face sex charges since TV host Jimmy Savile was exposed as a serial child molester after his death in 2011.
