It’s a gravy boat
Gravy is delicious
It’s a gravy boat
For your appetite
Spicy, nicey onions float
In the lovely gravy boat
If you should want to know
It’s not a train
Don’t buy a ticket
That’s not cricket
It’s a gravy boat
And it contains
Liquid velvet for the throat
Absurdly decadent and smooth
It’s a gravy boat, not a gravy train
I pour gravy on my food
It’s a gravy boat
It’s not a train
If it was then I’d complain
A train is always late
And I refuse to wait
Anyway, railway food’s appalling
Wait, I hear my dinner calling
It’s a s......... gravy boat
Now we’ve got that right
Bon, bon bon............
Bon appetite!  (or appetit?)

Anyway if there ever was a gravy train, (and I’m not saying there was,) the last train has gone forever, utterly broken, irreparable, too many  politicians scrabbling to climb aboard, (don’t you watch the news darling?)
