"Walking Down The Fulham Road"
From TheChels.info - The Chelsea Football Club Wiki
To the tune of "The Blaydon Races", a Geordie folk song written in the 1800s.
First sang at The Bridge around the late 1950s early 60s, with slight variations to the lyrics over the years.
Oh my lads, you should have seen 'em running,
Asked them why and they replied, the Chelsea boys are coming,
All the lads and lasses with smiles upon their faces,
Walking down the Fulham Ro-ad, to see the Chelsea aces.
