Fiery jack

Oh! I woke up with a backache
Backache! Backache!
I thought i ought to go to the first aid tin
Where i found something for my backache
Backache! Backache!
I rubbed in some cream and started to scream! Oh no
Chorus:
Firey jack firey jack- it's red hot on your back
Firey jack firey jack- believe me it does knack
Firey jack firey jack- it's red hot on your back
Firey jack
Now i had a back ache on me backache
Backache backache!
I jumped into the bath full of cold water
The firey jack had made me backache
Backache backache
I'm worse than before i can't take anymore
Oh no
Chorus
So if you do get a backache
Backache backache!
And you feel you have to reach for the first aid tin
Think! Life is not that bad with a backache
If you see a tin with firey jack in
Stay away
It's red hot... On your back... On your back
