Everything that makes Hall and Oates work is encapsulated in this song. It's soulful, it's yearning, it employs great musical touches in the forefront and in the background, it's got a killer hook, and it's got perhaps the quintessential Daryl Hall vocal moment (the "SHE'S GO-O-O-O-ONE" toward the end). The centerpiece of their second and best album, Abandoned Luncheonette (1973), it took a while to become a major hit because
their first label, Atlantic, had no idea what to do with them. It did not hit the top 10 until 1976, after H&O jumped to RCA and had a hit with Sara Smile, prompting Atlantic to try to cash in on that success.
A number of their songs have joint writing credits from Hall and Oates, but most of them were separate elements that were fused together; this is one of their few true writing collaborations from initial conception.
If you haven't heard the full Abandoned Luncheonette album, you really need to. It's one of those perfect records for kicking back with weed, wine or whatever and taking in every moment.
The album version is 5 minutes long and includes a sax solo that was cut from the single version.

They also shot an unintentionally hilarious video for it. One can only conclude they were on ludes during filming:
