Dylan sings to Haley in the song's music video.
In the Moonlight (Do Me) is a song written by Dylan and performed by his band. He wrote the song for Haley Dunphy and recorded a music video for it, in which they both starred. He first played the song for the family in the season one episode The Incident, and in the first verse started to convince Phil Dunphy and Claire Dunphy that it'd be alright for Haley to date Dylan, but they both immediately changed their minds once he began to passionately sing "I just wanna do you". However, they continued to be a couple.
Lyrics
Stars are falling from the sky
And you're the reason why
The moon is shining on your face
And I finally think its found it's place
(Chorus)
'Cause maybe, baby
I just wanna do you, do you
Do you wanna do me, do me,
Underneath the moonlight, the moonlight, tonight
Baby, maybe, maybe I will steal you, steal you
Just so I can feel you, feel you
maybe that would heal you, heal you on the inside
