Background
Kyle Broflovski comes to ask Mr. Mackey for advice about his brother's recent behavior. Mackey tries to use the IntelliLink computer software again, but initiates yet another popular song from the 1980's instead.
Lyrics
The heat is on, on the street
Inside your head, on every beat
And the beat's so loud, deep inside
The pressure's high, just to stay alive
'Cause the heat is on
Oh-wo-ho, oh-wo-ho
Caught up in the action I've been looking out for you
Oh-wo-ho, oh-wo-ho
(Tell me can you feel it)
(Tell me can you feel it)
(Tell me can you feel it)
The heat is on, the heat is on, the heat is on
The heat is on Oh it's on the street , the heat is - on
Oh-wo-ho, oh-wo-ho
Caught up in the action I've been looking out for you
Oh-wo-ho, oh-wo-ho
(Tell me can you feel it)
(Tell me can you feel it)
(Tell me can you feel it)
The heat is on, the heat is on, the heat is on
Oh it's on the street , the heat is - on
The shadows are on the darker side
Behind those doors, it's a wilder ride
You can make a break, you can win or lose
That's a chance you take, when the heat's on you
When the heat is on
Oh-wo-ho, oh-wo-ho
Caught up in the action I've been looking out for you
Oh-wo-ho, oh-wo-ho
(Tell me can you feel it)
(Tell me can you feel it)
(Tell me can you feel it)
The heat is on, the heat is on, the heat is on
It's on the street
The heat is on, the heat is on, the heat is on
Yeah it's on the street
The heat is on
