Hi Patrish, how'r ya doin'?

A song that's funny and doesn't take too much voice flamboyancy is "Sick note" by Pat Cooksey (or as it's also been called "Why Paddy's not at work today") You'll find it at The Dubliners' album "Celebration".

It's a howler!

And as the others have stated, find a song that YOU really like, and sing it in your own key. Not just a key that you can manage, but a key that lets your voice sound it's best. Meself, I've a voice that doesn't fit any standard keys, and I drive my band's fiddler and box-player up the walls by wanting keys like Eb and G#m.

Keep it up and good luck!
