Jumping Jack Flash,
It's a gas, gas, gas...

Well, the chorus works as it is. There's probably some monstrous curse lying in wait for anyone who messes with the verses, so I'll leave that to someone else...

re gases in the drink - I seem to remember hearing they used to bubble ether through it to liven up the poitín at one time. Maybe Nitrous Oxide (the old gas and air machine at the birth of a baby - do they still have that?)
