A Clean Sweep

Oh dear, what a to-do
 The orphan child is stuck in the flue
 We've pushed him and pulled him but all with no luck
 He's well and truly stuck
 The sweep said "Oh not again
 I must be overfeeding them
 We'll just light a fire to drive him up higher
 He'll soon wriggle free when he's hot"
 Oh dear, the room's full of smoke
 Open the window before we all choke
 He hasn't moved, but something's improved
 His screaming and sobbing has stopped
 The sweep looked up the chimney
 Little charred legs was all he could see
 "I know how to fix this, get another apprentice
 Go up and drag the dead one free"
 I need
 A clean sweep
 So they sent to the workhouse for another small child
 The parish obliged, all handshakes and smiles
 He pulled out the dead one, went back up to sweep
 He hasn't been seen for a week
 Clean sweep
 Clean sweep
 Clean sweep
 Clean sweep
 Clean sweep
 Clean sweep
 Clean sweep
 Clean sweep
