It’ll seen be time fir christmas
Time fir abody tae say
Hud yer weesht, it’s gettin late
Shut them peepers at end o the day
But, seen as yer ma’s heids hits e hay
Ye teeter oot o yer covers an mair
Yer lugs wirk sae hard, they shiver
An hush as ye go, near tae at door
Creepin doon yon steps fair sleekit
Teetin roun an roun, yer een openin wi frite
Shhhhhh em bells tinkle an jinngle
Ye look thru windae panes, an clap yer haun tae yer muth
A sleigh skiffs by, unner yer nose
Wi a flash fae rudolph, winkin is een
Shh lik a moose, scurry an shimmer
Up tae yer bed, afore santa slips doon yer lum
