In dance clubs remembered people would tweet this rhythm against disco music and clap. Built this in soundtrack pro with a whistle sample so electronic sounding and tempo not perfect (haven't learned how to nudge precisely) but fine for scratch. I put it against dance beat loop for first half then drop music out for second half. 48khz .wav file
I used it in my entry for the Metapop Remix This #317: Your Kiss Remix Contest.
I gave the original song a Disco treatment, including your Disco whistle (Cop whistle being tweeted at a Disco (with and without music)), obtained here on Freesound.org via Creative Commons Attribution 4.0 license.
[I used a small piece of the wav file, pitch-shifted it to suit]
