Sing us a song: Actually please stop!

I WISH I could sing.
Actually, if you listen to my mother, she'd say she wished I could still sing.
I was in a Tournament of the Minds competition once, where the team's most memorable moment was me singing my own lyrics to the Star Trek spoof song Star Trekkin'. After that, Mum decided that her little darling needed to get singing lessons so as to make the most of his precocious talent.
Unfortunately for Mum all little darling wanted to do was play sport (in particular cricket), and that soon died a slow and painful death. Since then breakouts of Spontaneous Karaoke Syndrome have met with the following conversation:

Mum:
"Why can't you still sing? You used to be able to sing really well."
Son:
"Let's see Mum. I know: when a child reaches a certain age, they go through this thing called puberty. This ushers in a range of changes to the child's body, which include in the case of males, extra body hair, facial hair, growth spurts and a deeper voice. Do you think having a changed voice might've finished any hopes of a national number 1 hit?"

Of course, this is the same mother who, when I was 19 and with reasonable sideburns, exclaimed at the top of her voice: "you've got stubble!"
Wow. Fancy that: nearly 20 and some signs of facial hair.
This isn't about Mum though (there isn't nearly enough room, and besides, she still has embarassing photos of me). This is about singing, and my current lack of ability to do that task with any kind of acknowledgement of how the original was sung.
Before I go much further, I must add I won a karaoke competition at a campsite in Rome by singing Frank Sinatra's New York, New York. I must also add that none of the other singers could carry a note more than two steps without dropping it. But other attempts at karaoke have ended with people either laughing at the dance moves, high-pitched voices or ability to forget about a verse rather than the sheer brilliance of the vocals.
At any rate, there's a "Jim Beam Idol" on up in Port Douglas for the next month. My plan is to head in on Sunday night, check out the competition, and see if it's worth embarassing myself yet again.
Should be fun.
