"I Love Saturday Night" was structured exactly like "TGIF", with hosts from each show rotating every week, down to its own set of branding graphics and a theme song. The intro to the lineup began with a red ABC logo encased inside an animated heart, which bounced around, and then off, the screen. Set against various-colored backgrounds (but most commonly blue), the lineup's title was then spelled out in the opening alongside views of animated suns, moons and palm trees. The theme song itself – with the lyrics "S-A-T-U-R-D-A-Y../ Saturday Night! / I Love Saturday / Saturday Night" – even had a calypso sound to it, with Jamaican-style male vocals. The last two lines of the theme were often sung over the show bumpers that led into the last commercial break of each show.
