DESCRIPTION:
Rolf Harris singing Never Smile at a Crocodile ... Never Smile at a Crocodile is a deleted song from the Walt Disney movie Peter Pan with the lyrics not heard, but the music was. Captain Hook gets eaten in the song. It was featured on the Disney Sing Along Songs video, Under the Sea with the scenes.
The tune is heard as an instrumental piece in Peter Pan whenever the Crocodile is getting close ... specially the ticking of the alarm clock that the croc has swallowed. It was written by Frank Churchill who wrote most of Disney's music in the 30s and the early 40s. Walt had planned to make Peter Pan in the early 40s and asked Frank to start writing the music for it. But when legal rights got in the way, the feature, and its music, was shelved.
Years later, Walt was finally able to make Peter Pan and asked Jack Lawrence, who was working on Sleeping Beauty at the time, to write some lyrics for the tune that Churchill wrote. Although the words were never heard in the movie, the song has gone on to be a popular children's song, especially in Australia ... thus Rolfie's rendition of it I guess.
Okay here comes them lyrics

LYRICS

Frank Churchill / Jack Lawrence (bit of Rolf)

Never smile at a crocodile
No, you can't get friendly with a crocodile
Don't be taken in by his friendly grin
He's imagining how well you'd fit beneath his skin (Rolf ha ha has)
Never smile at a crocodile
Never dip your hat and stop to talk awhile
Never run, walk away, say good-night, not good-day
Clear the aisle but never smile at Mister Crocodile
You may very well be well bred
Lots of etiquette in your head
But there's always some special case, time or place
To forget etiquette

(Spoken by Rolf)

Lets look up crocodile in the book
(clears throat) here it says ..
One positively must not wear a pleased expression on ones countenance when confronted by that large, lizard like, amphibious reptile which has long jaws, armored skin and webbed feet and which is known as ... the c r o c o d i l e.
It has been discovered that one simply cannot cherish an amicable and trustworthy relationship with the aforementioned species ... ohh! this is interesting!
In addition it is mandatory that one does not become irresistibly drawn into the erroneous belief that the lateral, open extension of his jaws means that you are utterly welcome. It is much more reasonable to assume that he is contemplating how you would look in a lizard suit ... hiiiis ... eh ha ha ha mmm

(Song resumes with three tic tocs)
Never smile at a crocodile
No, you can't get friendly with a crocodile
Don't be taken in by his friendly grin
He's imagining how well you'd fit beneath his skin
Where have I told you that before?
Never smile at a crocodile
Never tip your hat and stop to talk awhile
Dont be rude, never mock, throw a kiss, not a rock
But clear the aisle and never smile at Mister Crocodile
Look run a mile bet never smile at Mr. Croc-o-dile
Hey watch out! here comes one now!!!!
