The Mexican Whistler is the name of the tune Roger Whitaker whistled,I do believe.
Here is a list of songs with whistling in them - I think so anyway.

Slan,

I can whistle with my mouth, I can be pretty good too, but I only ever feel like whistling after playing my euphonium.
That sound personal.
I’ve been able to mouth whistle since I was about 5. I whistle much like I post on this board. To the point of annoying people.
It’s been an invaluable help in playing instruments. I learn new tunes by whistling them. Since I’m not encumbered by an instrument I often get cool harmonic ideas and can translate them into whatever I’m playing.
Someone once told me it was like having my own built in instrument.
My 3 year old grand daughter has learned to whistle now. She loves to imitate Grandpa.
That’s why I never play with my euphonium in front of her.
I managed to play a few things with my hands, but I never could get the range I wanted. About an octave and a fith was it. About the range and sound of an octarina.
I’d been whistling and fluting for an hour or two the other day and had to break off to take my wife out somewhere.
As we walked through town I was slightly behind her and I was whistling. Mouth whistling, I mean of course, the same tunes I had been practising before we’d left the house, just to get them into the brain. And it was one of those quiet, intimate little whistling noises like Martin’s referring to further up this thread.
“Bloody Hell!” she said. “Even out here I can hear some bugger on a tin whistle! Is there no getting away from it?”
I took that as an endorsement of my (mouth) whistling skill if not my (whistle) whistling!
Ho hum. 
j.i.
I can only get a little more than an octave. I knew someone in college who had two octaves.
I learned it on a backpacking trip I was leading. I got stuck with the s-l-o-w-e-s-t hiker I’ve ever known. My hands were just dangling there…
Hey! I can play the A part of Kesh jig! 
Why did I never think to play ITM on this instrument? Cool.

A person who can whistle…
is never bored and..
will always have something constructive to do..
is less likely to be lonely or depressed…
music is so good for the soul,
the great thing is, its something you can do whenever the urge grabs you
My father is a great whistler,
years of solitude on a farm, whistling kept him company

My brother can whistle like nobody’s business, little tongue-flutter and all. My father, however, could do the two-finger ear-splitter whistle so loud I thought my ears would . . . well, split.
I whistle constantly, but I’ll never be nearly as good as my brother.
I think some people have delicate hearing and while they might not complain about a fiddle or flute, the TW is just too harsh for their ears.
True. At work I often have to use chemicals in a fume hood which makes a lot of noise and rather isolates me, because I’m not able to really hear or talk to other people, even when the extraction is turned off. And apparently I start whistling or humming without even noticing. But the accoustics are very strange because people in the next room keep saying, “I knew it must be you working in the fume hood, I could hear you humming and whistling! I thought it was a radio at first!” (Apparently it’s also a dangerous spot to have a delicate conversation. One of my coworkers was in there talking quietly about some embarrassing health problems, and another girl had to run and tell him, “Be quiet, everyone can hear you out in the lab!”)
