You mean a Portuguese version of this....
(with apologies to the long deaded Spike Millgna, the great Irish spelling mistake??)
" Sideways through the sewers of the Strand on a Sunday afternoon
Sideways through the sewers of the Strand will be our honeymoon
Ankle deep folks in sludge dear we'll walk hand in hand
They do say that the sewers of the Strand are the finest in the land
Sideways through the sewers of the Strand will be paradise for two
Who cares if the atmosphere is blue
'Cause there's nothing wrong with a good old British pong
Sideways through the sewers of the Strand with you.... "
Ying tong iddle i po!
Seriously, done a search of the Portuguese web and nothing coming up.
Exits stage left singing "I'm walking backwar for Christmas across the Irish sea......."
