"It Must Be Love" is a song originally written and recorded in 1971 by Labi Siffre. However, the best known version was recorded by ska/pop band Madness in 1981.
The song was featured in the 1989 movie, The Tall Guy starring Jeff Goldblum, Rowan Atkinson and Emma Thompson. Suggs also appeared in the movie whilst singing this song. The single was reissued to tie in with the film but was not a hit on that occasion.
I never thought I'd miss you
Half as much as I do
And I never thought I'd feel this way
The way I feel about you
