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. --- jiminut
