This is a cover of Harry Nilssons song with the same name. Herb Alpert and the tijuana brass makes a wonderfull representation of the song, with very spare instrumentation. This is a song i can listen to on repeat for hours.
The song is really just this guy singing about how he cant live without her, and a guitar silently and spare playing along in the background, until the song explodes into lots of brass and horns playing with him.

Beatles were also fans by Harry Nilsson btw.
