it's called The Ketchup Song by Las Ketchup and it's massive in Europe but flopped here (stalled outside the top 40 i think). Which is a good thing (proves Brits still have some taste). It comes with it's own Whigfield-style dance. It is awful. Though the girls of Las Ketchup are decent eye-candy I suppose. As for where to get the lyrics...don't know, sorry.
personally i think its a great song! lol. but thats mt latin tackiness hsowing. if you want the lyrics to the english version (which is the one on tv and radio over here) then u will find them at http://80.56.120.204/song.php?id=2871
