In musical theatre, there's sometimes a fine line between the trite and the profound. At least for me, the simple message of "Yes" strikes deep chords. This sprightly song eschews its potentially saccharine subject by expounding on its thesis in colorful, conversational verses which list numerous everyday situations, many of them comically mundane, to make its case. It's hard to argue with a song that speaks literally to you (the lyrics are in second person) and so directly in your own language. Of course, Bob Fosse's lights, camera, action and Liza take it to another level.
