Should just keep to the classics like:
"Oh south London is wonderful"
"Give me a p"
"We're the right side"
"The Famous Alan Mullery went to Rome to sign the Pope"
"Super Palace"
"By Far the Greatest Team"
It's a great start to the Xmas album...
I'd also add (off the top of my head):
Ole, ole, ole, ole, Eagles
We're the red and blue army
Dum, dum, dum, dum, dum, dum, dum, dadum, PALACE!
[Insert Manager's name) Red and Blue Army
Hark now hear, the Palace sing (Very Xmassy)
We love you Palace
Who's that team we call the Palace
You've then always got generic fillers which seem to have faded (games gone), such as:
Let him Die
Who the f***ing hell are you?
Anything pertaining to 'northerners' (funniest when sang at Watford)
W*nker!
You don't know what you're doing
