This song sounds like a TV soundtrack from the 60s. I don't mean that in a bad way. I miss those old themes.
It starts off almost sounding like it was recorded in a garage. A really crappy garage, but by the first vocals breaking in it is a glorious sound quality. Lush strings, Horn, beautiful harmonies, and all woven together wonderfully.
The first 1:30 really does have that up beat happy and yet telling a little story kind of sound that you used to get in a TV theme. The horn is used constantly in this piece and it is amazing. such a versatile instrument. Then the change. We get amazing A Capella that then segues into a lightly instrumented (drum and string) choral segment. Then we kick back to the original up beat for a while. This drags down to a choral section I can only describe as what someone would play when the Romantic Interest in an action movie dies. Then we finish up with the fast beat again. This is a remarkably fun piece. The lyrics are witty and describe an office affair without getting ribald. The video takes it a bit beyond "an" office affair.
