we sang this a lot in my scout troop, 24th fife from templehall

as I remember
the maid of the mountain
she pissed like a fucking fountain
and the hairs on her dicky di do came down to her knees
one black one, one white one, one one with a bit of shite on
and one with a fairy light on to shine in the dark

there were a succession of versus following a set pattern

her brother was a stoker
with a cock like a fucking poker
and a da da da da da da
that da da da da

her ? was a ?
hung like a fucking donkey
cant remember any more.

?? was an italian
with a cock like a fucking stallion
and when he ???
he ???

the troops sing it in
the spike Milligan film AH my part in his downfall
with the works indistinct.
the tune is probably the Welsh song
the Ash Grove
and it is similar the the bawdry song
the Mayor of Bayswaters daughter
except is has two line versus.

my version differs from others
however this is just what we sang.

sorry I can remember so little
the thread is simultaneously discussing two different songs
also I'm not sure how far removed it is from Good Ship Venus/frigging in the rigging,

as an aside you might like Baracle Bill the Sailor
sung by Hoagy Charmichael with Bix beiderbeck in a cleaned up version
