Ok folks, I know this is a bit old, but it's one from the archives going back to 1978 and kindly supplied to me from Steven Walker, an old Grammar School lad from back in my own school year. We met a few weeks ago at an impromptu Old Boys' School Reunion with Simon Heathwood and Julien Wheatley and myself (Paul Skelton) at The Mogul in Dover and he promised to send me some archive material.
The School play was "Fire Raisers" and the photograph shows the entire cast for this play by Max Frish which was staged late April 1978.
I am hoping to get some more up to date photographs for this web site shortly.

Does anyone remember any of those shown above? If so I would be interested to hear from you. I can name a couple... There's Paul Beecham, left hand side, middle row and Dean Chatburn bottom row far right.
Regarding the 'Fire Raisers' photo, here are the names for you...
Back row left is Byron Chatburn in heavy make up and veil as Frau Knechtling (an old lady)
The firemen at the back from left to right are Rodney Haddrell, Peter Wicks, Steve Covell, Keith
Tolputt and Robin Bulow.
Don't know the bloke in the grey jumper, but next to him is Karen Alder from the girls grammar as
the maid and then Robert Dale on the end who was stage manager...(possibly the guy in grey
jumper was his assistant Michale Slater?)
Middle row from left is indeed Paul Beecham (in charge of lighting), then Simon Marples as Herr
Biedermann, Adrian Hodges as Schmitz a fire raiser, then me with foot over table as Eisenring
(another fire raiser) then Siobhan Doran from the girls Grammar school as Frau Biedermann.
Can't recall name of bloke front row left in white, but second is Peter Marsh, then Billy Newman,
Roger Lewis, Nick Cooper, can't place the guy in the school tie, but far right is Dean Chatburn.
Steve Walker.
