This is the best, most beautiful song Benji Hughes has ever written.
There are two things I have to point out.
One: Benji Hughes has an exceptional ability to write lyrics that fit his melodies as if the words and music spontaneously self-generated pre-figured. In this song, there is unbelievably sublime power in the way he sings the key line, "You're gonna wait a long time." How he hits down on those words, "wait," "long," "time," with such exhaustion. Those words are to be sung that way. They simply are.
Two: To have an idea of the attention to detail in "Waiting For an Invitation" (and to all songs on Benji Hughes's first album, A Love Extreme), look no further than the final 30 seconds of this song.
It goes out on a long fade to quiet. At a point where it's nearly gone, you might catch the subtle addition of numerous new instruments: Piano, synthesizers, etc. This sparse little song, in its final fading seconds, suddenly fills out into quite a lush arrangement, but it's audible for only a matter of moments before the track completely fades and is gone.
Long ago, I wrote a fan letter to Benji Hughes, my only fan letter, thanking him for these moments.
