According to Wikipedia "The current theme tune for the series is called "Match of the Day" and was written especially for the programme in 1970 by Barry Stoller, and has become so ubiquitous in British culture that it is associated not just with the programme but football in general. It is often incorrectly labelled with the title "Offside", which was actually the name of an alternative commercially-released version in 1970"
It's an audience favourite in many concert band repertoires. Whenever I've played it, in any of its many arrangements, it's been called 'Match of the Day'.
