A traditional British celebratory football crowd song.
The usual format is: :"We've won the cup, we've won the cup, ee aye addio, we've won the cup".
Variations are often made up on the spur of the moment.
The song perhaps first gained a wider audience at the 1965 FA Cup final at Wembley Stadium, when the singing by supporters of Liverpool F.C. was broadcast on TV and radio. Noticing the Queen had a red jacket on (Liverpool's team colours), the words were hastily changed to "Ee aye addio, the Queen's wearing red!".[1]
The origin of the song lies in the traditional British nursery rhyme The Farmer's in his Den.
