I am no April Fool, but I am a whistling fool. I can't help myself. I find myself whistling up a tune pretty much everyday and probably often to the annoyance of my coworkers.

In case you were unaware or underaware (tee hee) I want to inform you about the
International Whistlers Convention (IWC). It is held annually in April in the historic town of Louisburg, North Carolina, USA, the world's whistling capital. Believe it or not, but Loiusburg is not only home to the IWC, but to a Music Festival, an International School for Whistlers, and International Whistlers Museum!
At the convention there is a Whistling Competition. The IWC website has some suggestions for first time participants:
Competition in whistling contest is like other contests where you must be well prepared with rehearsals, develop self-confidence, and be motivated to win .
WHISTLING SCHOOL - Perhaps you may wish to register for classes in the International School for Whistlers in Louisburg preceding the contest. If you have stage fright, ask about how to overcome this common response when facing an audience.
SONG CHOICE - If you know an experienced or professional whistler, seek advise on what songs best fit your personal style.
PRACTICE - Practice, practice, practice, as in any performing art or sports activity. There is not a substitute.
Perhaps I should enter the whistling competition. If so, I need to start practicing. Song choice seems to be key. At work I stick with the classics - Christmas tunes (no matter what time of year), American Anthems, Disney's Robin Hood, and the C & H Pure Cane Sugar commercial. I think my contest entry would be the C & H Commercial jingle.
It troubles me greatly that no one seems to be familiar with C & H! It is one of the most fantastic jingles ever spun. The tune is that of "pearly shells". All you Don Ho/Hawaiian Elvis fans out there may be familiar with it. I found these lyrics online to jog your memories:
C & H

Pure Cane Sugar
From Hawaii
Sweetened by the sun
Island sugar, growing pure, so be sure, C&H,
pure cane sugar, that's the one!
For those of you out there that can't whistle, don't be jealous. You are not alone. No offense to Lauren Bacall, but it is not as easy as just putting your lips together and blowing. It takes skill. Some have it. Some don't. And don't feel bad. You can always hum.
