I sing everrrrrywhere.
I do karaoke every Saturday night at a local Restaurant/Bar. Everyone pretty much knows who I am there, haha.
I'd say I'm a good singer at the songs I do. I have a reeeeeally odd range. I can do really low, and I have a uncomfortably-high falsetto. But the point where my voice changes from regular singing to falsetto is right smack-dab where must songs sung by guys lay, so it's tough to find a good song to sing by a guy.
Songs I do a lot at karaoke::
"Tribute" - Tenacious D
"F*** Her Gently" - Tenacious D
"Enormous Penis" - DaVinci's Notebook
"I'll Be (500 Miles)" - The Proclaimers
"Runaway Train" - Soul Asylum
"Come On Eilieen" - Dexy's Midnight Runners
"Save the Last Dance For Me" - Michael Buble
"Spider-Man Theme" - Michael Buble
"Take On Me" - A-Ha
"I Believe In a Thing Called Love" - The Darkness
"Bother" - Stone Sour
"Losing My Religion" - R.E.M.
"I Can't Help Falling In Love With You" - Elvis
"I Will Always Love You" - Whitney Houson
"My Heart Will Go On" - Celine Dion
...yes, you read those last two right.

I save those ones as the last one for the night every once in a while. Always gets a great reaction, because at first everyone's quiet and looking at me like they're thinking "is this guy
serious?!?!", but I can actually sing them really well (and in the original octaves), so by the end everyone's cheering for me and will come up to me afterwards and compiment me.
...and I don't drink, so I'm ALWAYS sober. haha
