David Gilmour's son has been charged with violent disorder and theft.
The Pink Floyd guitarist's 21-year-old son Charlie Gilmour was one of seven people charged by the Metropolitan Police following their involvement in the protests against increased student tuition fees in London last month.
During the protests in the city's Trafalgar Square and Parliament Square on December 9, Charlie - who was adopted by David after his mother remarried - was photographed hanging from a Union Jack flag on the Cenotaph and he is also accused of stealing a mannequin leg.
He is now due at the City of Westminster Magistrates' Court on 10 February.
The day after the demonstrations, Charlie issued an apology, describing his actions as a "moment of idiocy" and admitted he did not know the monument commemorated Britain's war dead.
He was arrested on December 12.
The protests also saw rioters attack the car carrying Prince Charles and The Duchess Of Cornwall to the Royal Variety Performance as the demonstration descended into violence.
