Even rock stars have worries and frets about their kids and Pink Floyd's David Gilmour can't be very happy about his son Charlie.

Charlie Gilmour was sentenced to 16 months for disorderly conduct during student protests in London.  BBC News reported last week:

Gilmour, 21, was accused of throwing a bin at a convoy of cars containing Prince Charles, sitting on a protection officer's car and smashing a window.

The Cambridge University student, of Billingshurst, West Sussex, was bailed in May so he could finish his exams.

Kingston Crown Court heard he had taken LSD and valium before the incident.

I have a feeling David Gilmour has got a BIG headache right about now.
