Yes...Dave Bryant is right..I did write the final verse, but Dave's memory is a little shaky to the words. That listed doesn't scan! I wrote it 'coz the song didn't seem to have an ending. The verse is..

All of a sudden in the firemen rushed
And they saved us one by one!
But when they came to save the beer,
They found it had all gone!
And in the daily press next day
They solomly* did say
That they could not save the beer
'coz it had boiled away!

(Spoken) But we know better don't we!

Final chorus

*Doesn't look as if it's spelled right does it!

Best wishes,

Pete
