At the risk of being labelled 'Flatcapper' we played 'Entry of the Gladiators' before our league fixture with them on the 9/9/1970 and, promptly thrashed them 36-8
Eight months later we beat them 24-7 at Wembley, without the music
I seem to remember 'Banner Man' by Blue Mink was popular in the charts at the time too!
