jefferson's theme song...NOT

Serveral years ago there was a hip hop/rap song that played off the Jefferson's theme song (movin' on up) in the beginning and then moved into a rather catchy song about "partying like it's your birthday." The title and artist are a mystery to me. I have most of the lyrics but i have no clue who sings the song. Can you help?

Here's a rough sketch of the lyrics:

Why don't you come and get it and know forsure
Get your back up on the wall and your feet on the floor
something something somthing ????
Baby when i'm done i'm gonna show ya Baltimore
Right now we gonna party - then party some more
That's what the ole man say....party's like its my birthday. drinking to Thursday
Give me what'cha got -
hey what can i say, i finally got paid


If you can help me figure out the artist that would be wonderful!

The song is "Whoa Now" and it's by B Rich

"[Singing]
We're movin' on up
To the east side (We're movin' on up)
To a deluxe apartment in the sky
We're movin' on up (We're movin' on up)
To the east side (We're movin' on up)
We finally got a piece of the pie

[Verse 1]
Watch these come and gettin' em
Know fo sho
Yo, get your back up off the wall
And get your feet on the floor
You see the boy at the bar wit the glass so tall
When I'm done baby dogg
I'ma show you Baltimore
Right now we gon' party
Bacardi give me some more
It's off the rack the club packed
I'm two-cut like two doors
Of course I do my two-step
Give em too much
I mustered up bad
I drop ashes in my cup
I had enough they throwin' boes
See I'm swingin' this chick
I had my arm around this smut game
Puttin' in work
Before we work I got to book somethin'
So baby stop frontin'
I got the drink and the smoke
Ain't got to buy nothin'
Not bluffin'
It's goin' down understand me
I like my birds nasty
I burst in them cashmeres
Everything, and you know what I came for
Right now it's goin' down
Let me on the dance floor

[Hook x2]
Whoa now, that's what the old men say
I party like it's my birthday
Drinkin' and still thirsty
Whoa now, shorty gimme what you got
It's my car lot us, gettin' hotter

[Verse 2]
I came to shake a load off
So take you coat off
Mix drinks what you think
OJ and Smirnoff
I sip it all
Hey, what can I say
See I just got paid so I'm feelin' the swig
And I'm tryin' get laid
I'm buyin' drinks and they love it
Divas growin' cheaper
Hoochie bag and hoochie bucket
Takin' shots from my cousin
He don' know how to act
Came straight out the woods
And the club wit a sack
Like what you know no good
But I know I pimp nasty
Sneakers is off the meter
You can't help wit the clap
Can't help but the boogie
Get loose but don't push me
We came so deep
And we're all wearin' hoodies
All my eighty-dime soldiers
What you doin' tonight
Now, put yo eight-dimes up
You made enough for the night
Let's take a break
Let's spend some cake
You ain't enjoyin' your life
Yo, we been workin' all week
So we gon' do it tonight
Come on

[Hook x2]

[Verse 3]
All my east-side boys put ya guns up
Pull out the knife cuz we gon' party till the law comes
Them boys yellin' where they from
I represent too
They throwin' game signs
See, I'm throwin' W's (Westside)
I'm screamin' eighty-dubs
I swear to God it's goin down
I don't remember where I parked
And I'm stuck in town
One night in Baltimore
I bet ya never leave
My boy I know I can't help it but to love these streets
C'mon (We finally got a-)
C'mon, c'mon (We finally-)
C'mon, whoa now (We finally got a piece of the-)
C'mon, c'mon, whoa now (We finally-)
Whoa now (We finally-)
C'mon, c'mon, whoa now (We-we finally got a piece of the pie)
That's what the old men say
I party like it's my birthday
Drinkin' and still thirsty"
