The rain is falling through the mist of sorrow that surrounded me
The sun could never thaw away the the bliss that lays around me
Let it rain, let it rain
Let your love rain down on me
Let it rain, let it rain
Let it rain, rain, rain
Her life was like a desert flower burning in the sun
Until I found the way to love, it's harder said than done
Let it rain, let it rain
Let your love rain down on me
Let it rain, let it rain
Let it rain, rain, rain
Now I know the secret, there is nothing that I lack
If I give my love to you, you'll surely give it back
Let it rain, let it rain
Let your love rain down on me
Let it rain, let it rain
Let it rain, rain, rain
Now I know the secret, there is nothing that I lack
If I give my love to you, you'll surely give it back
Let it rain, let it rain
Let your love rain down on me
Let it rain, let it rain
Let it rain, rain, rain

AllMusic writer Matthew Greenwald notes, the song is "led by a striking electric guitar riff" with "the melody [being] woven elegantly around the simple, almost folk-like chord changes". Speaking to the lyrics, the critic recalled "the clever use of "rain" and "reign" regarding the power of love is the core here" and thinks that "Clapton and Bramlett utilize it quite well". Regarding the instrumental music work on the title, Greenwald finishes his song analysis by stating the "song has some striking instrumental sections, including a lovely, brief section by Stephen Stills".[2] The song is in the key of D major.[3] The melody has a strong resemblance to Stills' own song "Questions" recorded by both Buffalo Springfield and CSNY.
Like Clapton's "Strange Brew," the song was originally recorded with other lyrics. The original version titled "She Rides" is available on the expanded edition of the Eric Clapton album.
