What about singing "Sarpong" to Aerosmith's "Dream On"? You could just do the bridge and chorus bits:
Sing with me, sing for the year
Sing for the laughter, sing for the tear
Sing with me just for today
Maybe tomorrow, the good lord will take you away
Yeah, sing with me, sing for the year
Sing for the laughter, sing for the tear
Sing with me, just for today
Maybe tomorrow, the good Lord will take you away
Dream On Dream On Dream On Sarpong Sarpong Sarpong
Dream until your dream comes true
Dream On Dream On Dream On Sarpong Sarpong Sarpong
Dream until your dream comes through
Dream On Dream On Dream On Sarpong Sarpong Sarpong
Dream On Dream On Sarpong Sarpong
Dream On Dream On Sarpong Sarpong, AHHHHHHH
There, someone make a clever chant out of that...
