Several years ago I commented that Little Lies was about Lindsey's probable leaving Fleetwood Mac. I heard Christine say it in a 1987 interview how the little lies were how Lindsey kept winking saying he was staying in the band but she and the rest of the band knew he was going to leave. No one seemed to believe me. Here is a 1990 interview where Christine says it again at 7:00 how the song can be interpreted as a love song but there is a hidden and secret meaning about Lindsey going to leave the band. Earlier in the interview also has Stevie saying how she was not much around in the studio during Tango and they appreciated her "vibe" when she was there.
