Whats the name of that jazzy song?

Whats the name of the song that starts off with a very catchy and erotic/ detective style saxophone solo. after that a guy sings in a softish, comforting voice. the only lyrics i can remember are something like "I KNEW IT WOULD BE SO HARD"x2 but i cant remember exactly. He repeats the phrases he says twice and he says two phrases then it goes back to the solo. this happens about 3 full times. HELP I REALLY WANT TO HAVE THIS DAMN SONG!!!!

Maybe its Minnie the Moocher.
