(Newport Beach, CA, US)
I only heard this song once about a year ago being played from a neighbor's house, here's what I remember...
A slow, pretty, fairly new song (maybe 1-2 years) acoustic guitar duet with guy and girl singer
Song is about a relationship that's dealing with infidelity (the guy cheated) and the staleness of the relationship
The song is from the girls perspective
She loves him and wants to take a "holiday by (or at) the sea" which is one of the lyrics.
