"Sara" is the opening track of Fleetwood Mac's 1979 album "Tusk." The song was written by Lindsey Buckingham and is dedicated to his then-girlfriend and future wife, Christine McVie.
Buckingham and McVie met in 1974 when Buckingham joined Fleetwood Mac as the replacement for Bob Welch, and they began a romantic relationship shortly after. The song "Sara" is about Buckingham's feelings for McVie and his hesitation about their relationship.
In the lyrics, Buckingham sings, "Sara, you've got a smile that it seems to me/Reminds me of childhood memories," and "Sara, wherever we go/Don't you know what I mean, oh, Sara."
The song expresses the singer's deep affection and admiration for Sara and also explores the fear and complexities of commitment.
"Sara" was a commercial success, reaching number seven on the Billboard Hot 100 chart and number six in the UK Singles Chart. The song has become one of Fleetwood Mac's most beloved and recognizable songs.
It's worth noting that the song "Sara" is sometimes referred to as "Sara Smile," although that title is not officially recognized.
