AnTirKitten, That is the bowdlerised version of an obscene song called "Fall in and follow the band" the " and drinks tea" line when included often has an implied question mark after it.one of the "cleaner" verses
My husbands a Miner, a miner, a miner,
a very fine miner is he
all day he goes down, he goes down, he goes down,
and at night he comes up and goes down
If you need more/ want to shock the socks off someone drop me a line and I'll send what I have. Micca
