“To Sir, with Love” is the theme from the 1967 film To Sir, with Love. The song was written by Don Black and Mark London, husband of Lulu’s longtime manager Marion Massey.
“To Sir, with Love” was initially recorded by Lulu (with The Mindbenders, who also acted in the film). Her single was released in 1967 and reached number one on the Billboard Hot 100, remaining in the top position for five weeks and earning the number one position for the entire year. The song makes notable use of melisma.
In Lulu’s native UK, the song was never released in its own right, instead appearing as the B-side to the 1967 No. 11 hit “Let’s Pretend.”

Lyrics

Those schoolgirl days, of telling tales and biting nails are gone, But in my mind, I know they will still live on and on, But how do you thank someone, who has taken you from crayons to perfume? It isn’t easy, but I’ll try,

If you wanted the sky I would write across the sky in letters, That would soar a thousand feet high, To Sir, with Love

The time has come, For closing books and long last looks must end, And as I leave, I know that I am leaving my best friend, A friend who taught me right from wrong, And weak from strong, That’s a lot to learn, What, what can I give you in return?

If you wanted the moon I would try to make a start, But I, would rather you let me give my heart, To Sir, with Love
