On the Southside of Chicago 
Bobby boogie as the people 
Watch him dance step on the floor 
Ain't no match, you can 
Catch him some night dancing 
And the people in the disco 
Cheer for more 
And the music's fine 
He's the greatest dance star 
He'll blow your mind 
Well, it's hard to stay on top 
When you can't stop, no 
You're number one, yeah 
You're number one, yeah 
You know, yeah 
You're number one, yeah 
Now Jimmy's dressed in satin 
Laced with diamonds 
And he has moves just like 
A tiger in the night 
In every disco up in Frisco 
They're dancing 
His moves are strong 
To every song 
And the number one 
He had to know 
So he challenged Bobby 
On a TV show 
Like the?, got the stuff 
Got to show your stuff, yeah 
When you're number one, yeah 
You're number one, yeah 
You know, yeah 
You're number one, yeah 
People cleared the floor 
To let the dance begin 
Bobby moved and glided 
I thought his moves 
Would never end 
Jimmy turned and twisted 
As the ladies watched him dance 
His feet, they weaved 
That magic spell 
Put the crowd out in a trance 
Everybody, everybody was looking 
The music, the music, the music 
The music was cooking 
Those fast feet 
Hips and hands were moving 
And somehow when that 
Smoke got cleared away 
Jimmy was on the floor dancing 
And Bobby had simply 
Faded away 
So if you think 
That you're number one 
You can't claim the title 
Til the dance is done 
You're always gonna 
Make yourself a target 
To every new kid 
Who comes to town 
He's waiting to meet you 
At some disco 
When you're number one 
They try to shoot you down 
When you're number one, yeah 
You're number one, yeah 
You know, yeah 
You're number one, yeah
