Let's all sing together
Play up, Sky Blues
While we sing together
We will never lose
Proud Posh or COBBLERS
Oysters or anyone
They shan't defeat US
WE'LL fight 'til the game is won!
City! City! City!
The line including "Oysters" would be changed for each home game to include the nickname of the team we were playing that week and the song in its entirety would be printed in programme for that particular game. I Still have most of the programmes from those days.
