Couldn't get more Shibuya-kei than this song and its cute kitschy video. I'd been trying to track the YouTube video down for several minutes last night under the impression that it was a Pizzicato Five song, only to figure out that it was a Fantastic Plastic Machine contribution. Under the circumstances, the error was understandable since "Dear Mr. Salesman" has P5's delectable Maki Nomiya（野宮真貴）as guest vocalist and the music by FPM himself has all that wonderful 60s swing.
"Dear Mr. Salesman" was part of the seminal "The Fantastic Plastic Machine", FPM's debut album from October 1997, considered to be one of the audio bibles of Shibuya-kei. Excerpts of the song have been used ad nauseum as background music to introduce various segments on Japanese variety programming to the extent that I can only assume Tomoyuki Tanaka（田中知之）must have "bachelor pads" all over the jet-setting globe from all the copyright money he's made.
