Lyrics:

1) The 'Ba na na na' are horn sounds.
2) The 'Chakachaka' part is some sort of percussion.

'Rock N Roll Part II' by Gary Glitter

Ba na na na... Hey! Ba na na.
Ba na na na... Hey! Ba na na.
Ba na na na... Hey! Ba na na.
Chakachaka chakachaka chaka... (fans scream here: 'Go team!' substituting
whichever team they are rooting for)

Repeat forever.
