D…here are a couple of whistles for you. 😉
“Goodnight Irene”(one of my dad’s very favorite songs, when I was growing up…I used to think it was “Goodnight I Ring”)…
“Amazing Grace”…
I don’t have a good mic for doing music…just my headset mic with which I record my gaming videos. It has no way of screening out taking a breath between phrases (ugh).
Anyway…there you go…my whistling style. 😉
