I don't always whistle but when things are going well and am happy I tend to find myself whistling.
On the other hand my uptight wife will yell at anyone who whistles. Think it says something about her.
and don't even realize it until people start staring at me. I am sometimes loud.
Colonel Bogey March, This is the song from Bridge over River Kwia. This is my go to song for boring repetitive task. We learned it in Boy Scouts for when our scout master would take us on...
... You can book my whistling one-man band for weddings, graduations and yes... Funerals. And if you book now for your wedding, i will do your funeral for free .... Feel rather generous today. I might delete this offer tomorrow so hurry!
I like all kinds of music, and I whistle all kinds of songs, or probably just melodies I made up myself.
However, I often find myself whistling songs by the beatles. They just seem very whistle-able :)
