Here is a rare photo of David Bowie at the age of eight in 1955. At that time he was attending the Burnt Ash Junior School and he sang in the school choir. His voice was considered "adequate" but his recorder playing showed an "above-average musical ability". At the age of nine his dancing ability was said to be "vividly artistic" and "astonishing" for a child.
