Old theme song for What I Like About You?

Hope this helps a bit. Love Wikipedia.

The series takes its title from the song of the same name, which was originally released on a hit record by The Romantics in 1980. A cover version of the song, performed by the Canadian all-female rock group Lillix, was used as the theme song for the show. Lillix’s cover version of What I Like About You was also heard on the soundtrack of the 2003 remake of Freaky Friday and 13 Going on 30.

The theme was remixed and turned into a techno/dance style theme for the second season by Philip Steir (who composed the music for remainder of the series including the music to signal commercial breaks).

The pilot episode had a short opening sequence and the cast members’ names were only shown in the teaser. The sequence solely consisted of scenes of New York sights with an animation of the show’s logo with the letters “I” and “o” enlarging, the word “what” sliding in from the left side of the screen, the word “like” fluctuating in size, the “ab” and “ut” in “about” sliding in from both sides of the screen and the letters in the word “you” sliding up from the bottom of the screen appearing to smack the rest of the title into place. This same animation was carried over to the season one opening titles.

The first season’s opening sequence mixed home movies of three sets of two girls representing younger versions Holly and Val for six seconds in the beginning and two seconds near the end of the sequence, along with shots of Amanda Bynes and Jennie Garth sticking their tongues out at the camera for four seconds near the beginning and two seconds near the end of the sequence and scenes from the first four episodes, all shown on rounded rectangles which for most of the sequence moved from right to left sliding in from the right side of the screen. Video headshots of each cast member with their names were shown every two to five clips. Newer episode scenes were inserted twice during the first season. First, in the episode “Valentine’s Day” and again in the episode “The Fix-Up”, which replaced nearly all of the clips from the first four episodes.

The opening title sequence used for the rest of the series featured the show’s cast in front of digitally inserted scenes of New York at night. The sequence was modified twice. The first time the sequence was modified was in the episode “The Incredible Shrinking Group” when Stephen Dunham’s video headshots were removed and the video of the cast after the show’s title was replaced with video of Amanda Bynes and Jennie Garth. Stephen Dunham’s video headshot was replaced with video of the cast in front of the New York skyline. The second modification was in “The Longest Night of the Year” when all traces of Michael McMillian were removed from the sequence. Added footage was put in to replace the footage of McMillian. A yellow streak of light was added to the sequence as well.
