please please, can somebody tell me the theme song and lyrics to the sitcom "live-in". Help it has been killing me for nearly 5 years

If I remember correctly, "Live-In" used part of "Happy Together", the 1967 hit by The Turtles, for its theme. Gladys Knight (singing with someone else) covered the song for the theme song. You can find the lyrics to the full song at http://warpedworld.net/Lyrics/HappyTogether-Turtles.html.
