I vaguely remember not getting selected for the choir but the song had the line "DH Lawrence and DNA" ... "Newton's laws, two world wars" and also the welsh town llanfairpwllgogeryn...gogogoch.
It was to go and sing with other schools in Birmingham I'm absolutely convinced.
I'm sure I didn't imagine this although it is slightly possible I have misremembered.
I've googled but can't find the song!
