Peter played Dennis Dunstable (portraying a teenager, despite the fact he was well into his 20s) in Please Sir! - and the spin-off series The Fenn Street Gang.
He was perhaps more familiar to some of us (in what I thought was a brilliant performance) as peculiar nerd Ralph in Dear John (far left in the picture, http://www.bbc.co.uk/comedy/dearjohn/).
He was a semi-regular in Agony with Maureen Lipman (playing one half of a gay couple) and also appeared in Emmerdale and Dixon Of Dock Green. Later in life he wrote, directed and starred in panto.
R.I.P.
