Now, Paul, you can't tell us this without finding us the lyrics. ... 
Well, since you asked:
The Greasy Chip Butty Song is a football chant mainly sung by the supporters of Sheffield United football club, but has been adopted and adapted by fans of several other teams including Rotherham United and St Helens Rugby League. The originator of the song is unknown however it was first sung during Sheffield United's first match of the 1985-86 season in Division 2. This was a Blades 3-1 away win at Stoke City's Victoria Ground on 17th August 1985.
To the tune of Annie's Song by John Denver:
You fill up my senses
Like a gallon of Magnet
Like a packet of Woodbines
Like a good pinch of snuff
Like a night out in Sheffield
Like a greasy chip butty
Like Sheffield United
Come fill me again....
Na Na Na Naa Naa Naaaaa, ooo!
To a native of Sheffield the words are probably self explanatory; the words celebrate the many pleasures that can be had in Sheffield, culminating in the target of the fan's adoration, Sheffield United.
Magnet refers to John Smith's Magnet, a beer once widely available in Sheffield. Some people claim that the second line is really Like a gallon of maggots. Maggots are obtained from fishing tackle outlets in denominations of imperial pints and hence this version would not be unreasonable, as fishing is popular in the region and hence a gallon of maggots would mean a good day out fishing.
Woodbines refers nostalgically to a once popular brand of strong cigarette.
Snuff is ground tobacco for sniffing up the nose.
A Greasy chip butty can be purchased in any of the many local fish and chip shops. Butty is a slang word for sandwich, so a chip butty is simply a sandwich where the filling is chips, ideally greasy and sprinkled with salt and vinegar. Generally, a white sandwich bap will be used for the bread. In Sheffield, these are simply known as Breadcakes.
The song itself is a plaintive rally-cry by the fans of Sheffield United. It is usually heard on commencement of the home games played at 'beautiful' downtown Bramall Lane, the home of the club, and sporadically throughout away matches.
