Gib sang "Ring The bell second mate" at the BBC club this week.
I had to read this thread as I remembered "Click go the shears" and wanted to check which was earlier.
Being a lover of parodies I also recalled that the Australian government parodied "lick go the shears" to advertise decimalisation:

IN COME THE DOLLARS:
Words by Ted Roberts for The Decimal Currency Board

In come the dollars and in come the cents
to replace the pounds and the shillings and the pence.
Be prepared folks when the coins begin to mix
on the 14th of February 1966.

Clink go the cents folks clink, clink, clink.
Changeover day is closer than you think.
Learn the value of the coins and the way that they appear
and things will be much smoother when the decimal point is here.

In come the dollars and in come the cents
to replace the pounds and the shillings and the pence.
Be prepared folks when the coins begin to mix
on the 14th of February 1966.

Cheers Nigel
