Musical Episodes in Non-Musical TV Shows

Music on television is a big trend, from musical series such as Glee and the new Smash, to musical competitions (American Idol, The Voice, The X Factor).  Even shows that have no musical connection whatsoever still sometimes offer an episode or two with musical numbers.  Sometimes, it's so quirky and brilliant that it works. Other times, it's so out of left field, it leaves viewers scratching their heads in confusion.

Here are some that come to mind (linked to samples from YouTube).

7th Heaven

Batman: The Brave and the Bold

Buffy the Vampire Slayer

Chicago Hope




Grey's Anatomy



The Simpsons

That 70s Show

Xena: Warrior Princess
