Pr’haps cause there weren’t any CDs in the early 60s.
You may be referring to Robson and Jerome (not exactly a household term in the US but apparently big sellers in the UK).
Getting somewhat back on track, it’s a pretty easy tune on the whistle. A way to practice the aural tradition. See if you can play like a Muppet.
Best wishes.

Steve,
I must confess that I did not realize that The Drifters did the original. I hope I get a get out of jail free card as I was only seven years old in 1962.

I would like to add one method of silencing a whistle that I use for almost all my whistles.
I place a piece of a PVC pipe over the window and slide it around to open more or less and slightly adjust the volume from almost mute to full.
It is very simple to make and can be applied, with varied degrees of ease, on most whistles.

I also seldom use putty, tape and the paper clip depending on the type of silencing I’m looking for, not a big fan of the “whisper method” though.

Yes, and that ended well as I recall. Like I said, Homeland Security.
Yep, that was it. Just looked at the video, which was apparently shot in New York. The Twin Towers appear in the background a bit as they dance on the roof. Things have changed.
My point on the JT vs. Drifters thing was more to say that the version that might come to mind might depend on one’s age and home location. Good songs have a habit of coming round again over time and being re-woven into the fabric of new generations. Kudos to King and Goffin for writing a good one..
Nice work!

Isn’t this about the same concept as the tone ring on Parks whistles?

Chicken or egg?
Actually the first time I heard of the silencing ring on Parks’ whistles I tried to figure out if the system used was similar to mine (or more appropriately the other way around) but ultimately couldn’t tell for sure.
Now that you’re telling me I feel happy to have come by myself to the same solution of a renowned maker.
Similar devices have been used for years IME. Folks do come up with variations on the theme periodically. I used a section of bicycle tire inner tube (narrow road size) with a slot cutout that did the same thing with the added characteristic of being flexible and able to be stretched to fit over a variety of irregularly shaped mouthpieces. It worked better on some whistles than others.
My guess is that Ugg came up with a similar mechanism right after the girls around the campfire started to become annoyed by his new whistle invention.

Actually, it sort of started in a similar way for me.
I first tried with a paper ring with a thin slot cut through it because I didn’t want the tape I used initially to leave the whistle sticky after some time, but as you can imagine paper doesn’t work well with moisture and admittedly it wasn’t that easy to use and not as effective.
So one day, after I finished drilling and hammering a poor pvc pipe for the umpteenth whistle, while I was cleaning up the table, a scrap struck my imagination so I cut a slot in it as well and tried it. It worked, but cutting that slot was a pain and there was no flexibility in opening and closing the window. That’s when the final idea came.
This is a great idea, but doesn’t the shape of the slot opening stretch as well providing inconsistent results?
Indeed!
