TiVo queried the Twitterverse for our favorite television theme songs. Tunes from Friends, The Fresh Prince, and Greatest American Hero were offered up as contenders, with my initial submission being the diddy describing The Jeffersons ascension. After conferring with Friends (of my own), Cheers is a no brainer for any list of top TV show songs. After all, when the series concluded May 20th, 1993 it seemed as if the entire restaurant where I barbacked sang the tune together that evening. So who else belongs on this list? And do we include instrumentals?
