Music of So Weird The series featured original songs sung by both Mackenzie Phillips and Alexz Johnson. Songs sung by Mackenzie Phillips included the theme "In the Darkness", "Another World", "Rebecca", "The Rock" and "Love is Broken". Each of the songs usually tied into the theme of the episode they were featured in. For example, "Rebecca" was featured in the episode "Rebecca" which dealt with Molly's former best friend of the same name who vanished when she was 13 years old. A compilation of Molly's songs was featured in the episode "Encore." During seasons one and two, a music video that starts out with a talking scene between Jack and Clu and then Molly asks them and Fi to go to bed while they act jovial and happy, was aired. It featured over 62 clips from seasons one and two. It was the song "In the Darkness". It starts out with Jack and Clu fooling around, Clu howling and someone strumming a guitar. Molly comes to them in the RV and tells them it is time for her second show and that means bed. Fi closes her computer and says goodnight. She looks sad. Jack hugs Molly goodnight. Clu tells Molly to "knock em dead' or something or Break A Leg, Molly mocks his voice and says, "Thank you Clu" and shakes his hand. They leave. She goes out of the RV and starts to sing in a strange set. "Last Night Blues," was the only occasion Cara DeLizia had to sing during her stint on the show. The song was supernaturally transferred to the characters from a murdered blues musician. Season 3 mainly used the music of Alexz Johnson.
