歌词
Let's go!

Don't wantcha for the weekend, don't wantcha for a night
I'm only interested if I can have you for life, yeah
Uh, I know I sound serious and baby I am
You're a fine piece of real estate, and I'm gonna get me some land

Oh, yeah
So, don't try to run honey, love can be fun
There's no need to be alone when you find that someone

[Chorus:]
(I'm gonna getcha)
I'm gonna getcha while I gotcha in sight
(I'm gonna getcha)
I'm gonna getcha if it takes all night
(Yeah, you can betcha)
You can betcha by the time I say "go," you'll never say "no"
(I'm gonna getcha)
I'm go
