Have things become so bad that BUFC need to look to bland power ballads as "good songs". Jesus wept.
How about something with a bit of spirit and joviality? The bridge in "You Can Call Me Al" by Paul Simon surely deserves a shout. I'd be perfect for goal celebrations and chants. You could even incorporate a arm-action thing akin to the "dance" Chris Waddle/Terry Butcher and co did.
The chorus has a very easy an adaptable 5 line verse, too.
Or what about "Fiesta" by The Pogues? again, more joviality, more upbeat chords. And more importantly, an easily chanted/sung melody, perfectly suited to a football terrace.
