An Old-Fashioned Piano Party

S3 E20: When Grace (Debra Messing) frets that she and Will (Eric McCormack) might drift apart like their similar friends, she impulsively buys an expensive piano which she hopes will cement their mutual bond and love for music - or at least give her an excuse to perform a lot of show tunes. Meanwhile, when Jack is dumped by his latest romantic interest, he vents his grief by writing trashy novels, which instantly draw Karen's (Megan Mullally) passionate attention.
