The rhyme typically gives it away...e.g.
The Band - "The Shape I'm In"
Now two young kids might start a ruckus
You know they feel you trying to [del]shuck[/del] fuck us
Oh, you don't know the shape I'm in
----
Sam Cooke - "Another Saturday Night"
Another Saturday night
And I ain't got nobody
I got some money 'cause I just got paid
Now, how I wish I had someone to talk to
[del]I'm in an awful way[/del] I really need to get laid
