I've wanted to start this thread for awhile, so the time is now.
How many classic TV shows had their themes carved from songs written for the series. Song that ran well past what aired as the theme song. EX: The theme to Angie was taken from the song "Different Worlds".
so, with this in mind
Which theme songs came right from the single (edited from the version released as a single) as was
The Monkees, Welcome Back Kotter, Love American Style.
and how many came from different versions than the single version (the TV theme sounding notably different than the full length single)
Angie, Happy Days, Friends
