I'm looking for the lyrics of a song which is either called 'The Coca-Cola Song', or 'The Coca-Cola Always Tastes the Same'.

The chorus goes :-

Oh I have seen the Mona Lisa,
The Leaning tower of Pisa,
Been to Rome and back again;
But the only thing I know
is that everywhere I go,
The Coca-cola always tastes the same.

It used to be sung a lot in the 60's but I haven't hrard it since; I'd very much like to sing it again.
